    The source of energy for almost all life on earth is:

    • Sunlight

    • Fungi

    • Water

    • Animals

    Correct Answer
    A. Sunlight
    Explanation
    Sunlight is the correct answer because it is the primary source of energy for almost all life on Earth. Through the process of photosynthesis, plants and some other organisms are able to convert sunlight into chemical energy, which is then used by other organisms through the food chain. Sunlight provides the energy needed for plants to grow, which in turn provides food for animals and other organisms. Without sunlight, life on Earth would not be possible as it is the driving force behind the Earth's ecosystems.

    How do biotic resources differ from abiotic resources? 

    • Biotic resources are more important than abiotic resources

    • Biotic resources are limited and abiotic are unlimited.

    • Biotic resources are living and abiotic resources are nonliving

    • Biotic resources are non-living and abiotic resources are living

    Correct Answer
    A. Biotic resources are living and abiotic resources are nonliving
    Explanation
    Biotic resources refer to living organisms or materials derived from living organisms, such as plants, animals, and microorganisms. On the other hand, abiotic resources are nonliving components of the environment, such as air, water, minerals, and sunlight. This means that biotic resources are associated with life and can reproduce or regenerate, while abiotic resources do not possess these characteristics. Therefore, the correct answer is that biotic resources are living and abiotic resources are nonliving.

    An example of a biotic resource in a forest ecosystem is:

    • Waterfall

    • Tree

    • Cliff

    • Rock

    Correct Answer
    A. Tree
    Explanation
    A tree is an example of a biotic resource in a forest ecosystem because it is a living organism that plays a crucial role in the ecosystem. Trees provide habitat for various animals, contribute to the oxygen cycle by releasing oxygen, and help in maintaining the balance of carbon dioxide in the atmosphere through photosynthesis. They also provide food and shelter for many organisms and play a vital role in nutrient cycling. Therefore, a tree is a biotic resource that supports the functioning and diversity of the forest ecosystem.

    Examples of abiotic resource in a pond ecosystem is:

    • Temperature

    • Algae

    • Fish

    • Frogs

    Correct Answer
    A. Temperature
    Explanation
    Temperature is an abiotic resource in a pond ecosystem because it is a non-living factor that affects the ecosystem. Temperature can influence the growth and reproduction of organisms in the pond, as well as their metabolism and behavior. It plays a crucial role in determining the distribution and abundance of species in the ecosystem.

    Predation (hunting) is a positive benefit to the population of prey organisms because it tends to keep 

    • Populations low

    • Populations high

    Correct Answer
    A. Populations low
    Explanation
    Predation (hunting) is a positive benefit to the population of prey organisms because it tends to keep populations low. When predators hunt and consume prey, it reduces the number of prey individuals in the population. This helps to prevent overpopulation and competition for limited resources within the ecosystem. By keeping prey populations in check, predation helps to maintain a balanced and sustainable ecosystem, ensuring that resources are not depleted and allowing for the survival and reproduction of other species in the community.

    Jacob went to school in a short sleeve shirt.  A cold front blew in while he was in school.  While waiting for his bus he started shivering. Jacob decided to skip the bus and run home. After he start running his shivering stopped.  How would you explain this?

    • Shivering made him warmer.

    • Running made Jacob warmer

    • He made it home

    • Shivering and running have nothing to do with each other.

    Correct Answer
    A. Running made Jacob warmer
    Explanation
    When Jacob started shivering, it indicated that his body was trying to generate heat to keep warm. However, shivering alone was not enough to increase his body temperature significantly. When Jacob decided to run, the physical activity increased his heart rate and blood circulation, generating more heat in his body. This increased heat production from running helped to warm up Jacob, causing his shivering to stop. Therefore, running made Jacob warmer.

    Which of these food chains is in the correct order?

    • Caterpillar, water lily, frog, snake

    • Water lily, caterpillar, frog, snake

    • Snake, frog, caterpillar, water lily

    • Water lily, frog, caterpillar, snake

    Correct Answer
    A. Water lily, caterpillar, frog, snake
    Explanation
    This food chain is in the correct order because it follows the sequence of energy transfer from one organism to another. The water lily is a producer that provides energy to the caterpillar. The caterpillar is then consumed by the frog, which in turn is preyed upon by the snake. This order represents the flow of energy and the relationship between the organisms in the food chain.

    An example of a consumer in a pond ecosystem is:

    • Water lily

    • Algae

    • Reed

    • Frog

    Correct Answer
    A. Frog
    Explanation
    A consumer in a pond ecosystem refers to an organism that obtains its energy by consuming other organisms. In this case, a frog is the correct answer because it feeds on other organisms such as insects, small fish, and even other frogs. It is higher in the food chain and plays a crucial role in maintaining the balance of the ecosystem by controlling the population of its prey. Water lily, algae, and reed are not consumers as they are either producers (water lily and algae) or decomposers (reed), which obtain energy from sunlight or dead organic matter.

    Two abiotic resources that affect an ecosystem are: 

    • Temperature and animals

    • Plants and animals

    • Water and bacteria

    • Soil and water

    Correct Answer
    A. Soil and water
    Explanation
    Soil and water are two abiotic resources that affect an ecosystem. Soil provides the necessary nutrients and minerals for plants to grow, while water is essential for the survival of all living organisms. Both soil and water play a crucial role in maintaining the balance and health of an ecosystem.

    An animal that eats only plants is a :

    • Primary consumer

    • Secondary consumer

    • Teritary consumer

    • Primiary producer

    Correct Answer
    A. Primary consumer
    Explanation
    A primary consumer is an animal that eats only plants. This means that it relies on plants as its main source of energy and nutrients. Primary consumers are typically herbivores, such as cows, rabbits, and deer, that feed directly on plant material. They occupy the second trophic level in a food chain or food web, as they are the first consumers in the chain that obtain energy from producers (plants). Therefore, the correct answer is "Primary consumer."

    Decomposers are important to ecosystems because they:

    • Are at the highest level of the energy pyramid

    • Change simple compounds into more complex ones

    • Convert light energy into sugars through photosynthesis

    • Make nutrients available for producers to use

    Correct Answer
    A. Make nutrients available for producers to use
    Explanation
    Decomposers are important to ecosystems because they make nutrients available for producers to use. Decomposers break down dead organic matter and waste materials, releasing essential nutrients such as nitrogen, phosphorus, and carbon back into the environment. These nutrients can then be taken up by plants and other producers to support their growth and development. Without decomposers, the nutrients would remain locked in dead organisms and unavailable to other organisms in the ecosystem, leading to a depletion of essential resources and a disruption of the food chain.

    In an energy pyramid, the bottom level represents:

    • Consumers

    • Producers

    • Scavengers

    • Decomposer

    Correct Answer
    A. Producers
    Explanation
    In an energy pyramid, the bottom level represents producers. Producers are organisms, such as plants, that are capable of converting sunlight into energy through the process of photosynthesis. They are the primary source of energy in an ecosystem and form the foundation of the food chain. By producing their own food, producers provide energy for the organisms at higher trophic levels, such as consumers, scavengers, and decomposers. Therefore, the correct answer is producers.

    An example of a producer is:

    • Fungus

    • Caterpillar

    • Bird

    • Water Lily

    Correct Answer
    A. Water Lily
    Explanation
    A producer is an organism that can produce its own food through photosynthesis. Fungus, caterpillar, and bird are not examples of producers as they do not have the ability to produce their own food. However, a water lily is an example of a producer because it can undergo photosynthesis and produce its own food using sunlight, water, and carbon dioxide.

    In an energy pyramid, the lowest level has: 

    • Less energy than the top level

    • Less energy than the second level

    • More energy than the top level

    • The same amount of energy is available to a consumer

    Correct Answer
    A. More energy than the top level
    Explanation
    In an energy pyramid, the lowest level has more energy than the top level. This is because the energy flow in an ecosystem is unidirectional and decreases as it moves up the pyramid. The lowest level, which consists of producers such as plants, captures energy from the sun through photosynthesis and stores it in the form of chemical energy. As this energy is transferred to herbivores and then to carnivores at higher levels, some energy is lost as heat or used for metabolic processes, resulting in less energy being available at each subsequent level. Therefore, the lowest level has the most energy available compared to the top level.

    All the following are examples of limiting factors for a population EXCEPT:

    • Space

    • Food

    • Time

    • Weather

    Correct Answer
    A. Time
    Explanation
    Time is not a limiting factor for a population because it does not directly impact the population's growth or survival. Space, food, and weather can all limit the population size by affecting the availability of resources and suitable habitats. However, time itself does not impose any constraints on the population's ability to grow or thrive.

    Which one of the following answers is not an example of a mammal attempting to maintain homeostasis?

    • Sweating

    • Shivering

    • Dehydration

    • Goose-bumps

    Correct Answer
    A. Dehydration
    Explanation
    Dehydration is not an example of a mammal attempting to maintain homeostasis because it is a condition where the body loses more fluids than it takes in, leading to an imbalance in the body's water levels. Homeostasis refers to the body's ability to maintain a stable internal environment, and dehydration disrupts this balance. Sweating, shivering, and goosebumps are all mechanisms used by mammals to regulate body temperature and maintain homeostasis.

    A food chain shows: 

    • One possible pathway for energy

    • Many possible pathways for energy

    • The amount of energy available to a producer

    • The amount of energy available to a consumer

    Correct Answer
    A. One possible pathway for energy
    Explanation
    A food chain shows one possible pathway for energy as it depicts the transfer of energy from one organism to another in a linear sequence. Each organism in the chain consumes the organism below it, transferring energy along the chain. This representation helps us understand how energy flows through an ecosystem and how organisms depend on each other for energy.

    Which of the following is an example of an ecosystem?

    • Air, water, grass, badgers

    • Air, water, sunlight, and soil

    • Hawks, mouse, badgers, and eagles

    • Grass, trees, bushes, and flowers

    Correct Answer
    A. Air, water, grass, badgers
    Explanation
    Air, water, grass, and badgers are all components of an ecosystem. An ecosystem is a community of living organisms (such as plants, animals, and microorganisms) interacting with their non-living environment (such as air, water, and soil). In this case, air and water provide the necessary elements for life, grass serves as a primary producer, and badgers represent one of the many animal species that inhabit the ecosystem.
