Le Hw4.1.3b - Quiz

These questions deal with energy pyramids. think about the flow of energy.


Questions and Answers
  • 1. 

    The graph below represents the amount of energy stored in each level of an energy pyramid. Which level most likely represents the autotrophs in the energy pyramid?

    • A.

      1

    • B.

      2

    • C.

      3

    • D.

      4

    Correct Answer
    A. 1
    Explanation
    The autotrophs, also known as producers, are organisms that can produce their own energy through photosynthesis or chemosynthesis. They are typically found at the bottom of the energy pyramid as they convert sunlight or inorganic compounds into organic matter, which is then consumed by other organisms. In the given graph, level 1 has the highest amount of energy stored, indicating that it represents the autotrophs in the energy pyramid.

    An energy pyramid is represented below. The energy for use by organisms in level A originally comes from

    • A.

      Producers

    • B.

      The Sun

    • C.

      Level B

    • D.

      Level D

    Correct Answer
    B. The Sun
    Explanation
    The energy for use by organisms in level A originally comes from the Sun. Producers, such as plants, capture sunlight through photosynthesis and convert it into chemical energy. This energy is then passed on to other organisms in the food chain, including those in level A. The Sun is the ultimate source of energy for all living organisms on Earth, as it provides the necessary light and heat for photosynthesis and other metabolic processes.

  • 3. 

    An energy pyramid is shown below. Which graph best represents the relative energy content of the levels of this pyramid?

    Correct Answer
    D.
  • 4. 

    Base your answers  on the diagram below, which represents a pond food web, and on your knowledge of biology. Which energy pyramid most accurately shows the energy relationships between three organisms in this food web?

    Correct Answer
    B.
  • 5. 

    The diagram below represents a typical energy pyramid. Which level in the pyramid includes autotrophs?

    • A.

      A

    • B.

      B

    • C.

      C

    • D.

      D

    Correct Answer
    D. D
    Explanation
    Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis. They are typically found at the base of the energy pyramid as they are the primary producers of energy. In the given diagram, level D is at the bottom of the pyramid, indicating that it includes autotrophs.

    The diagram below represents an energy pyramid. Which organisms would most likely be found at level A?

    • A.

      Birds

    • B.

      Worms

    • C.

      Mammals

    • D.

      Algae

    Correct Answer
    D. Algae
    Explanation
    Level A in an energy pyramid typically represents the producers, which are the organisms that convert sunlight into energy through photosynthesis. Algae are photosynthetic organisms that can be found in aquatic environments, such as oceans, lakes, and ponds. They are able to capture sunlight and convert it into chemical energy, making them the most likely organisms to be found at level A of an energy pyramid.

    Base your answers to the question below on the diagram below that represents an energy pyramid in a meadow ecosystem and on your knowledge of biology. Which species would have the largest amount of available energy in this ecosystem?

    • A.

      A

    • B.

      B

    • C.

      C

    • D.

      E

    Correct Answer
    A. A
    Explanation
    In an energy pyramid, the amount of available energy decreases as you move up the pyramid. The producers, which are represented by A in the diagram, have the largest amount of available energy because they convert sunlight into energy through photosynthesis. As you move up the pyramid to the primary consumers (B), secondary consumers (C), and tertiary consumers (E), the available energy decreases because each level relies on the level below it for energy. Therefore, A would have the largest amount of available energy in this ecosystem.

    Base your answers to the question below on the diagram below that represents an energy pyramid in a meadow ecosystem and on your knowledge of biology. Which two organisms are carnivores?

    • A.

      A and B

    • B.

      A and E

    • C.

      B and D

    • D.

      C and E

    Correct Answer
    D. C and E
    Explanation
    Organisms C and E are carnivores because they are located at the highest trophic level in the energy pyramid. Carnivores are organisms that obtain their energy by consuming other animals. In this energy pyramid, organism C is positioned at the top, indicating that it is a tertiary consumer, while organism E is positioned just below, indicating that it is a secondary consumer. Both of these organisms rely on consuming other animals for their energy needs, making them carnivores.

    Base your answers to the question on the energy pyramid below and on your knowledge of biology Which level includes organisms that receive their energy from level B?

    • A.

      A

    • B.

      B

    • C.

      C

    • D.

      D

    Correct Answer
    C. C
    Explanation
    Level C includes organisms that receive their energy from level B. In an energy pyramid, each level represents a trophic level, with producers (such as plants) at the bottom and consumers (such as animals) at higher levels. Level B represents the primary consumers, which are herbivores that consume the producers for energy. Level C represents the secondary consumers, which are carnivores that consume the primary consumers for energy. Therefore, level C includes organisms that receive their energy from level B.

    Base your answers to the question on the energy pyramid below and on your knowledge of biology Which level includes organisms that get their energy exclusively from a source other than the organisms in this ecosystem?

    • A.

      A

    • B.

      B

    • C.

      C

    • D.

      D

    Correct Answer
    A. A
    Explanation
    The energy pyramid represents the flow of energy in an ecosystem, with each level consisting of organisms that obtain energy from the level below. In this case, level A is the producer level, which includes organisms such as plants that can produce their own energy through photosynthesis. These organisms do not rely on other organisms for energy and instead get their energy from sunlight. Therefore, level A includes organisms that get their energy exclusively from a source other than the organisms in this ecosystem.
