    What three processes form the water cycle?

    • Condensation, evaporation, precipitation

    • Mutualism, commensalism, parasitism

    • Host, niche, prey

    Correct Answer
    A. Condensation, evaporation, precipitation
    Explanation
    The water cycle is the continuous movement of water on, above, and below the Earth's surface. The three processes that form the water cycle are condensation, evaporation, and precipitation. Condensation occurs when water vapor cools and changes back into liquid form, forming clouds. Evaporation happens when water from bodies of water, plants, or soil turns into water vapor due to heat from the sun. Precipitation is the process where water droplets in the clouds combine and fall to the Earth's surface as rain, snow, sleet, or hail. These three processes work together to maintain the water balance on Earth.

    This is the process by which organisms change and develop to become better suited to their environments.

    • Natural selection

    • Food chain

    • Predation

    Correct Answer
    A. Natural selection
    Explanation
    Natural selection is the process by which organisms change and develop to become better suited to their environments. It is a fundamental mechanism of evolution, where individuals with advantageous traits are more likely to survive and reproduce, passing on their traits to future generations. Over time, this leads to the adaptation and improvement of species, as those with less favorable traits are less likely to survive and reproduce. Natural selection is driven by environmental factors and acts as a powerful force in shaping the diversity and complexity of life on Earth.

    Rate this question:

  • 10. 

    The process by which a gas changes to a liquid.

    • Evaporation

    • Condensation

    • Nitrogen fixation

    Correct Answer
    A. Condensation
    Explanation
    Condensation is the correct answer because it refers to the process in which a gas changes to a liquid. This occurs when the gas molecules lose energy and come together to form liquid droplets. It is the opposite of evaporation, where a liquid changes to a gas. Nitrogen fixation, on the other hand, is a biological process in which atmospheric nitrogen is converted into a form that plants can use.

    Rate this question:

  • 11. 

    An organism that obtains energy by feeding on other organisms.

    • Consumer

    • Prey

    • Scavenger

    Correct Answer
    A. Consumer
    Explanation
    A consumer is an organism that obtains energy by feeding on other organisms. This means that it consumes and derives nutrients from other living organisms in order to survive and obtain the energy it needs. Consumers are an important part of the food chain as they help transfer energy from one organism to another. They can be herbivores, carnivores, or omnivores, depending on their diet. Unlike prey, which refers to the organism that is hunted and consumed by another organism, a consumer can actively seek out and consume other organisms for energy. A scavenger, on the other hand, primarily feeds on dead or decaying organisms.

    Rate this question:

  • 12. 

    A consumer that eats both plants and animals/meat.

    • Herbivore

    • Carnivore

    • Omnivore

    Correct Answer
    A. Omnivore
    Explanation
    An omnivore is a consumer that eats both plants and animals/meat. This means that it has a diverse diet and can obtain nutrients from both plant-based and animal-based sources. Unlike herbivores, which only eat plants, and carnivores, which only eat meat, omnivores have the ability to digest and utilize nutrients from both types of food. This adaptability allows omnivores to thrive in a variety of environments and gives them more options for obtaining the necessary nutrients for survival.

    • Evaporation

    • Condensation

    • Precipitation

    Correct Answer
    A. Precipitation
    Explanation
    Precipitation refers to the process by which water in the atmosphere condenses and falls back to the Earth's surface in the form of rain, snow, sleet, or hail. In the given scenario, heavy drops of the waterfall falling back to the Earth can be considered as precipitation as it involves the water droplets condensing in the atmosphere and then precipitating down to the ground.

    Rate this question:

  • 21. 

    This is a carnivore that feeds on the bodies of dead organisms.

    • Predator

    • Scavenger

    • Parasite

    Correct Answer
    A. Scavenger
    Explanation
    A scavenger is an organism that feeds on the bodies of dead organisms. They play an important role in ecosystems by helping to clean up and recycle organic matter. Unlike predators, scavengers do not actively hunt and kill their prey. Instead, they rely on finding and consuming already dead organisms. This behavior allows scavengers to take advantage of a food source that would otherwise go to waste. Therefore, the correct answer for this question is scavenger.

    Rate this question:

  • 22. 

    What are the three types of interactions among organisms?

    • Evaporation, condensation, precipitation

    • Natural selection, mutualism, parasitism

    • Competition, predation, symbiosis

    Correct Answer
    A. Competition, predation, symbiosis
    Explanation
    Competition, predation, and symbiosis are three types of interactions among organisms. Competition occurs when organisms compete for limited resources, such as food or territory. Predation refers to the interaction where one organism, the predator, hunts and kills another organism, the prey. Symbiosis is a mutually beneficial relationship between two different species, where both organisms benefit from each other's presence. These three types of interactions play a crucial role in shaping ecosystems and determining the survival and success of different species.

    Rate this question:

  • 23. 

    A close relationship between two species that benefits at least one of the species.

    • Mutualism

    • Symbiosis

    • Competition

    Correct Answer
    A. Symbiosis
    Explanation
    Symbiosis refers to a close relationship between two species that benefits at least one of the species. In symbiotic relationships, the species involved interact closely with each other, often relying on each other for survival or reproduction. This can include mutualistic relationships where both species benefit, as well as parasitic or commensal relationships where one species benefits at the expense or without affecting the other. Therefore, symbiosis is the correct answer as it encompasses a broader range of relationships compared to mutualism, which specifically refers to a mutually beneficial relationship.

    Rate this question:

    The pattern of overlapping food chains in an ecosystem.

    • Food chain

    • Food web

    • Nitrogen fixation

    Correct Answer
    A. Food web
    Explanation
    A food web is a more complex and realistic representation of the feeding relationships in an ecosystem compared to a food chain. It includes multiple interconnected food chains, showing the flow of energy and nutrients through various organisms. Each organism can have multiple predators and prey, resulting in a more accurate depiction of the complex interactions within an ecosystem. Nitrogen fixation, on the other hand, refers to the process by which nitrogen gas is converted into a usable form by certain bacteria and is not directly related to the pattern of overlapping food chains.

    Rate this question:

    Can free nitrogen in the atmosphere be used by most living things?

    • Yes

    • No

    Correct Answer
    A. No
    Explanation
    Most living things cannot use free nitrogen in the atmosphere because they lack the ability to convert atmospheric nitrogen into a usable form. Nitrogen fixation, the process of converting atmospheric nitrogen into a form that can be used by living organisms, is carried out by certain bacteria and some plants. These organisms have the necessary enzymes to break the strong triple bond between nitrogen atoms and convert nitrogen gas into ammonia or other compounds that can be used by living things.

    Rate this question:

    • Decomposer

    • Nodules

    • Parasite

    Correct Answer
    A. Nodules
    Explanation
    Nodules are bumps that form on the roots of plants and contain bacteria. These bacteria have a symbiotic relationship with the plant, as they are able to convert atmospheric nitrogen into a form that the plant can use for its growth and development. This process is known as nitrogen fixation. Therefore, nodules play a crucial role in the nitrogen cycle and help in enriching the soil with essential nutrients for the plant's survival.

    Rate this question:

  • 30. 

    A relationship in which one species benefits but the other species is not helped nor harmed.

    • Parasitism

    • Mutualism

    • Commensalism

    Correct Answer
    A. Commensalism
    Explanation
    Commensalism is a type of relationship where one species benefits while the other is neither helped nor harmed. In this relationship, one organism takes advantage of resources or shelter provided by another without affecting it positively or negatively. It is different from mutualism, where both species benefit, and parasitism, where one species benefits at the expense of the other. Therefore, commensalism is the correct answer as it describes a relationship where one species benefits while the other remains unaffected.
