About This Quiz


We welcome you to take this quiz to learn about the energy flow in the ecosystem. An ecosystem is made of flora, fauna as well as landscape. The biotic and abiotic components play a role in maintaining life on Earth; energy is essential for an ecosystem's homeostasis. The questions in our quiz are curated to help you better understand the topic. Please read each question carefully and choose the answer that best answers the question. You can collect your scorecard once you've completed the quiz. Remember to share the quiz with your friends! Good luck!

    In an energy pyramid, which way does energy transfer?  

    • From the top of the pyramid to the bottom

    • From the bottom of the pyramid to the top

    • None of these

    • Both of these

    Correct Answer
    A. From the bottom of the pyramid to the top
    Explanation
    In an energy pyramid, energy transfers from the bottom to the top. This is because the primary producers, such as plants, capture energy from the sun through photosynthesis and convert it into chemical energy. This energy is then transferred to the primary consumers, such as herbivores, when they consume the plants. The energy continues to transfer up the pyramid as it is consumed by secondary consumers, such as carnivores, and so on. Therefore, the energy flow in an energy pyramid is unidirectional, moving from the bottom to the top.

    An energy pyramid is used to show _________.   

    • The layout of organisms in any order seen fit

    • The amount of energy in the universe

    • The amount of energy at each trophic level

    • None of the above

    Correct Answer
    A. The amount of energy at each trophic level
    Explanation
    An energy pyramid is used to show the amount of energy at each trophic level. It represents the flow of energy through different levels of a food chain or food web. The pyramid shape represents the decreasing amount of energy available as it moves up the trophic levels, with the producers at the base having the most energy and the top consumers having the least. This visual representation helps to illustrate the energy transfer and efficiency between different organisms in an ecosystem.

    As one progresses from level D to level A in this pyramid, what happens to the amount of stored energy?   - ProProfs

    As one progresses from level D to level A in this pyramid, what happens to the amount of stored energy?  

    • Increases

    • Decreases

    • Remains the same

    • None of the above

    Correct Answer
    A. Decreases
    Explanation
    As one progresses from level D to level A in the pyramid, the amount of stored energy decreases. This is because energy is lost as it moves up the trophic levels. At each level, organisms use some of the energy for their own metabolism and activities, and the rest is lost as heat. Therefore, as energy flows through the food chain, there is less and less energy available at higher trophic levels, resulting in a decrease in the amount of stored energy.

    Which of these best describes the relationship shown by this Kelp Forest Ecosystem pyramid?   - ProProfs

    Which of these best describes the relationship shown by this Kelp Forest Ecosystem pyramid?  

    • The Giant Sea Bass is a predator of the Sheephead

    • The Giant Sea Bass is the prey of the Sheephead

    • Sea Urchins are the prey of the Kelp.

    • Sheepheads are the predator of the Giant Sea Bass

    Correct Answer
    A. The Giant Sea Bass is a predator of the Sheephead
    Explanation
    The pyramid illustrates the flow of energy in a kelp forest ecosystem, with different species occupying different trophic levels. Here's a breakdown of the levels:
    Level 1 (Producers): Kelp
    Level 2 (Primary Consumers): Sea Urchin (herbivores that feed on kelp)
    Level 3 (Secondary Consumers): Sheephead (predators that feed on sea urchins)
    Level 4 (Tertiary Consumers): Giant Sea Bass (top predator that feeds on sheephead)
    From this, the best description of the relationship shown is:
    "The Giant Sea Bass is a predator of the Sheephead."
    This correctly reflects the trophic interaction where the giant sea bass is a higher-level predator feeding on the sheephead.

    If birds eat insects that feed on corn, which pyramid level would birds occupy? - ProProfs

    If birds eat insects that feed on corn, which pyramid level would birds occupy?

    • A

    • B

    • C

    • D

    Correct Answer
    A. B
    Explanation
    Birds would occupy pyramid level B. In a food pyramid, each level represents a different trophic level or feeding level. Birds are secondary consumers, meaning they eat primary consumers. In this scenario, the insects that feed on corn would be the primary consumers, and the birds that eat those insects would be the secondary consumers. Therefore, birds would occupy pyramid level B.

    Look at the following energy pyramid. If the producers have 7000 kcal of energy, how much energy will be available for the Sheephead ? fish?   - ProProfs

    Look at the following energy pyramid. If the producers have 7000 kcal of energy, how much energy will be available for the Sheephead ? fish?  

    • 7 kcal

    • 70 kcal

    • 700 kcal

    • 7000 kcal

    Correct Answer
    A. 70 kcal
    Explanation
    The energy pyramid shows the flow of energy in an ecosystem, with producers at the bottom and consumers at higher levels. Each level of the pyramid represents a trophic level, and energy is transferred from one level to the next. In this case, if the producers have 7000 kcal of energy, the energy available for the Sheephead, which is a consumer at a higher trophic level, would be less than the energy available for the producers. Therefore, the correct answer is 70 kcal, as it represents a lower amount of energy available for the Sheephead compared to the producers.

    Which level of this food pyramid represents the largest amount of organisms? - ProProfs

    Which level of this food pyramid represents the largest amount of organisms?

    • Tertiary consumers

    • Secondary consumers

    • Primary consumers

    • Producers

    Correct Answer
    A. Producers
    Explanation
    Producers, such as plants, represent the largest amount of organisms in the food pyramid. They are capable of converting sunlight into energy through photosynthesis, which makes them the primary source of energy for all other organisms in the ecosystem. As a result, there are typically more producers than any other level in the food pyramid.

    Which number on the diagram below shows the location of the secondary consumers?  - ProProfs

    Which number on the diagram below shows the location of the secondary consumers? 

    • 3

    • 2

    • 1

    • 4

    Correct Answer
    A. 3
    Explanation
    Number 3 on the diagram shows the location of the secondary consumers. Secondary consumers are organisms that eat primary consumers, which are shown as number 2 on the diagram. Therefore, number 3 represents the location of organisms that consume the primary consumers, making them the secondary consumers.

    Explanation
    Sea urchins live on less energy than bass.
