  • 2. 

    Nonliving parts of the environment such as soil, water, sunlight. 

    • Decomposers

    • Biotic

    • Abiotic

    • Scavenger

    Correct Answer
    A. Abiotic
    Explanation
    The correct answer is "Abiotic" because nonliving parts of the environment such as soil, water, and sunlight are considered abiotic factors. Abiotic factors play a crucial role in shaping ecosystems and influencing the distribution and abundance of living organisms. They provide the physical and chemical conditions necessary for life but do not have the ability to reproduce or undergo metabolic processes. Examples of abiotic factors include temperature, humidity, pH levels, and availability of nutrients.

    Rate this question:

  • 3. 

    All the living things in an environment such as bacteria, plants, and animals.

    • Biotic

    • Food Chain

    • Limiting factors

    • Autotrophs

    Correct Answer
    A. Biotic
    Explanation
    The term "biotic" refers to all living things in an environment, including bacteria, plants, and animals. Biotic factors play a crucial role in shaping ecosystems and influencing the interactions between organisms. They can include factors such as predation, competition, and symbiosis. Understanding the biotic components of an environment is essential in studying the relationships and dynamics within ecosystems.

    Rate this question:

  • 4. 

    The place where an animal or plant lives - fields, oceans, forests, streams, deserts.

    • Habitat

    • Niche

    • Population

    • Community

    Correct Answer
    A. Habitat
    Explanation
    Habitat refers to the specific place or environment where an animal or plant naturally lives or is typically found. It encompasses various types of ecosystems such as fields, oceans, forests, streams, and deserts. A habitat provides the necessary conditions, resources, and interactions for a particular species to survive and thrive. It includes both biotic factors (living organisms) and abiotic factors (non-living factors) that influence the species' existence.

    Rate this question:

  • 5. 

    An organism that eats only plants

    • Prey

    • Producer

    • Autotroph

    • Herbivore

    Correct Answer
    A. Herbivore
    Explanation
    A herbivore is an organism that eats only plants. This means that it obtains its energy and nutrients solely from consuming plant material. Unlike predators or omnivores, which consume a variety of organisms including animals, a herbivore's diet consists exclusively of plant matter. This dietary specialization is reflected in the anatomical and physiological adaptations of herbivores, such as specialized teeth for grinding plant material and a longer digestive system to extract nutrients from cellulose. Overall, herbivores play an important role in ecosystems by controlling plant populations and energy flow through the food chain.

    Rate this question:

  • 6. 

    An organism that uses light energy to make its own food. 

    • Consumer

    • Parasite

    • Host

    • Autotroph

    Correct Answer
    A. Autotroph
    Explanation
    An autotroph is an organism that can produce its own food using light energy. This process is known as photosynthesis. Autotrophs, such as plants and some types of bacteria, are able to convert sunlight into chemical energy, which they use to synthesize organic compounds like glucose. Unlike autotrophs, consumers obtain their energy by consuming other organisms, parasites rely on a host organism for survival, and hosts provide a living environment for parasites. Therefore, the correct answer is autotroph.

    Rate this question:

  • 7. 

    An organism that survives by eating animals.

    • Prey

    • Producer

    • Carnivore

    • Autotroph

    Correct Answer
    A. Carnivore
    Explanation
    A carnivore is an organism that survives by eating animals. Carnivores are typically at the top of the food chain and have adaptations such as sharp teeth and claws to help them capture and kill their prey. They obtain their energy and nutrients by feeding on other animals, which makes them different from producers (organisms that make their own food) and autotrophs (organisms that can produce their own food through photosynthesis or chemosynthesis). Therefore, the correct answer is carnivore.

    Rate this question:

  • 8. 

    An organism that consumes dead organisms and organic waste, example – bacteria, fungus

    • Decomposer

    • Parasite

    • Herbivore

    • Producer

    Correct Answer
    A. Decomposer
    Explanation
    Decomposers are organisms that consume dead organisms and organic waste, such as bacteria and fungi. They play a crucial role in the ecosystem by breaking down dead matter and recycling nutrients back into the environment. Unlike parasites, which rely on a living host for their sustenance, decomposers obtain their energy from non-living organic matter. Herbivores, on the other hand, consume living plants for their nutrition, while producers are organisms that can produce their own food through photosynthesis. Therefore, the correct answer is decomposer.

    Rate this question:

  • 9. 

    A representation of interconnected food chains that show more complex feeding relationships between producers, consumers, and decomposers.

    • Limiting Factor

    • Biodiversity

    • Food Web

    • Ecology

    Correct Answer
    A. Food Web
    Explanation
    A food web is a representation of interconnected food chains that show more complex feeding relationships between producers, consumers, and decomposers. It illustrates how energy and nutrients flow through an ecosystem, highlighting the interdependence of different organisms. Unlike a food chain, which only shows a linear sequence of who eats whom, a food web demonstrates the multiple connections and interactions among various species. It provides a more comprehensive understanding of the ecosystem's dynamics and the balance of energy and resources within it.

    Rate this question:

  • 10. 

    An animal that hunts and kills other animals for food which limits the growth of a population.

    • Predators

    • Competition

    • Herbivore

    • Prey

    Correct Answer
    A. Predators
    Explanation
    Predators are animals that hunt and kill other animals for food, which in turn limits the growth of the prey population. By preying on other animals, predators help control the population size of their prey, preventing it from becoming too large and causing imbalances in the ecosystem. This relationship between predators and prey is crucial for maintaining the overall health and stability of the ecosystem.

    Rate this question:

  • 11. 

    All the different populations that live and interact in an environment.

    • Community

    • Population

    • Niche

    • Biosphere

    Correct Answer
    A. Community
    Explanation
    Community refers to all the different populations that live and interact in an environment. It includes various species that coexist and interact with each other in a specific area. This term encompasses the relationships, interactions, and dependencies between different organisms within a particular ecosystem. It is an important concept in ecology as it helps in understanding the dynamics and functioning of ecosystems.

    Rate this question:

  • 12. 

    Food and or home for a parasite.

    • Scavenger

    • Decomposer

    • Host

    • Consumer

    Correct Answer
    A. Host
    Explanation
    The correct answer is "Host" because a host refers to an organism that provides food and/or shelter for a parasite. In this context, the parasite relies on the host for its survival and reproduction. The host may or may not be harmed by the parasite, but it is essential for the parasite's life cycle.

    Rate this question:

  • 13. 

    A carnivore that feeds on the bodies of dead organisms; a vulture.

    • Host

    • Scavenger

    • Parasite

    • Autotroph

    Correct Answer
    A. Scavenger
    Explanation
    A scavenger is a carnivore that feeds on the bodies of dead organisms, such as a vulture. Scavengers play an important role in the ecosystem by cleaning up and recycling dead organic matter. They help prevent the spread of diseases by removing carcasses, and they also provide a source of food for other animals. Unlike parasites, which live on or in a host organism and derive nutrients from it, scavengers primarily rely on dead organisms for their food source.

    Rate this question:

  • 14. 

    Another name for heterotroph; An organism that obtains its energy from producers.

    • Scavenger

    • Consumer

    • Parasite

    • Decomposer

    Correct Answer
    A. Consumer
    Explanation
    A consumer is an organism that obtains its energy from producers, which makes it an appropriate alternative name for a heterotroph. Consumers are organisms that feed on other organisms, either by consuming them directly or by consuming their byproducts. They cannot produce their own energy through photosynthesis or other means, so they rely on consuming other organisms for their energy needs. Therefore, the term "consumer" accurately describes an organism that obtains its energy from producers.

    Rate this question:

  • 15. 

    An organism that produces their own food; example green plants

    • Consumer

    • Heterotroph

    • Herbivore

    • Producer

    Correct Answer
    A. Producer
    Explanation
    Producers are organisms that have the ability to produce their own food through the process of photosynthesis. They use sunlight, water, and carbon dioxide to create glucose and oxygen. Green plants are a prime example of producers as they contain chlorophyll, which allows them to convert sunlight into energy. This energy is then used to produce food for themselves and other organisms in the ecosystem.

    A straight line representation that identifies specific feeding relationships between prey and predator.

    • Food Chain

    • Succession

    • Food web

    • Energy Pyramid

    Correct Answer
    A. Food Chain
    Explanation
    A food chain is a straight line representation that identifies specific feeding relationships between prey and predator. It shows the flow of energy from one organism to another in an ecosystem. Each organism in the chain is dependent on the organism below it for energy. The food chain helps us understand how energy is transferred and how different organisms are interconnected in an ecosystem.

    Rate this question:

  • 17. 

    Organisms that cannot make their own food (consumer)

    • Heterotroph

    • Producer

    • Prey

    • Abiotic

    Correct Answer
    A. Heterotroph
    Explanation
    Heterotrophs are organisms that cannot produce their own food and rely on consuming other organisms for their energy and nutrients. They obtain their food by either directly consuming other organisms (predators) or by consuming dead organic matter (decomposers). This is in contrast to autotrophs, such as plants, which can produce their own food through photosynthesis. Heterotrophs play a crucial role in the food chain as consumers, as they obtain energy from the lower trophic levels and transfer it to higher trophic levels.

    Rate this question:

  • 18. 

    The process by which one community is replaced by another; bedrock - lichens - mosses- grasses - trees and shrubs - forest

    • Ecological succession

    • Habitats

    • Energy Pyramid

    • Ecological Niche

    Correct Answer
    A. Ecological succession
    Explanation
    Ecological succession refers to the process by which one community is gradually replaced by another over time. It starts with the colonization of bare rock by lichens, which break down the rock and create soil. Then, mosses and grasses begin to grow, followed by trees and shrubs, eventually leading to the formation of a forest. This sequence of changes in the community structure is known as ecological succession.

    Rate this question:

  • 19. 

    Struggle between organism for the same resources. This keeps the size of a species population in check. 

    • Predators

    • Limiting factors

    • Biodiversity

    • Competition

    Correct Answer
    A. Competition
    Explanation
    Competition refers to the struggle between organisms for the same resources. This struggle helps to regulate the size of a species population by limiting the availability of resources. When resources are limited, organisms must compete with one another for access to these resources, such as food, water, and shelter. This competition can lead to the survival and reproduction of only the fittest individuals, while others may be unable to obtain enough resources to survive. Therefore, competition plays a crucial role in maintaining the balance of populations within an ecosystem.

    Study of how living things interact with one another and the environment.

    • Food Web

    • Ecosystem

    • Ecology

    • Ecological Succession

    Correct Answer
    A. Ecology
    Explanation
    Ecology is the study of how living things interact with one another and the environment. It focuses on understanding the relationships between organisms and their surroundings, including the interactions between different species, the flow of energy and nutrients through ecosystems, and the impact of human activities on the natural world. Ecology helps us understand the complex web of life and how all living organisms are interconnected. It provides valuable insights into conservation efforts, biodiversity, and the sustainability of ecosystems.

    Rate this question:

  • 21. 

    The specific role played by an organism in the ecosystem. If there is more than one species in the same role there is competition and a species will be eliminated.

    • Niche

    • Heterotroph

    • Predator

    • Population

    Correct Answer
    A. Niche
    Explanation
    The correct answer is "Niche". A niche refers to the specific role or position that an organism occupies within its ecosystem. It includes the organism's habitat, its interactions with other species, and its resource utilization. Each species has a unique niche that allows it to survive and reproduce. When there are multiple species occupying the same niche, competition occurs, and one species may outcompete and eliminate the other.

    Rate this question:

  • 22. 

    All the individual of a single species living in an area. Ants in an any hill.

    • Host

    • Community

    • Population

    • Limiting Factor

    Correct Answer
    A. Population
    Explanation
    The term "population" refers to all the individuals of a single species that live in a particular area. In this case, the ants in an ant hill would constitute a population. A population can be defined as a group of organisms of the same species that interact with one another and share the same habitat. Therefore, "population" is the correct answer in this context.

    Rate this question:

  • 23. 

    The largest population of any single species an area can hold that is determined by the available energy, water, oxygen and minerals available as well as by the interaction of organisms (food supply and competition).

    • Carrying capacity

    • Limiting Factor

    • Ecological Niche

    • Ecological Succession

    Correct Answer
    A. Carrying capacity
    Explanation
    Carrying capacity refers to the maximum population size that an environment can sustain indefinitely, given the available resources and conditions. It is determined by factors such as energy, water, oxygen, minerals, and the interactions between organisms, including competition and food supply. When a population exceeds the carrying capacity of its environment, it may experience resource depletion, competition, and other negative impacts that can lead to a decline in population size.

    Rate this question:

  • 24. 

    A subdivision of the environment that includes all living and nonliving portions of the planet.

    • Ecological Niche

    • Habitat

    • Population

    • Biosphere

    Correct Answer
    A. Biosphere
    Explanation
    The biosphere refers to the subdivision of the environment that encompasses all living and nonliving components of the planet. It includes all ecosystems, such as forests, oceans, deserts, and even the atmosphere. The biosphere is a dynamic system where living organisms interact with each other and with their physical surroundings. It is the highest level of organization in ecology and plays a crucial role in maintaining the balance of life on Earth.

    Rate this question:

  • 25. 

    An organism that survives by living and feeding on other organisms, but rarely kill them.

    • Parasites

    • Scavengers

    • Decomposers

    • Carnivores

    Correct Answer
    A. Parasites
    Explanation
    Parasites are organisms that survive by living and feeding on other organisms, but they rarely kill them. They rely on a host organism for their survival and obtain nutrients from it without causing immediate death. This relationship is often parasitic, as the host is harmed to some extent, but not usually killed. Parasites can be found in various forms, such as fleas, ticks, and lice, and they have adapted to live off their hosts while minimizing harm to ensure their own survival.

    • Food Web

    • Energy Pyramid

    • Food Chain

    • Ecological Succession

    Correct Answer
    A. Energy Pyramid
    Explanation
    An energy pyramid is a diagram that illustrates the flow of energy through an ecosystem. It shows the different trophic levels, starting with producers at the bottom, followed by primary consumers, secondary consumers, and so on. The pyramid shape represents the decrease in available energy as it moves up the food chain, with each level consuming only a fraction of the energy from the level below. This diagram helps to visualize the transfer of energy and the interdependence of organisms within an ecosystem.
