This food web reveals that, as matter flows through trophic levels,

• matter from consumers, such as the green lynx spider, is eventually recycled by decomposers, such as a fungus.

• matter from producers, such as the cutleaf daisy, is immediately recycled by decomposers, such as a bacterium.

• matters from all organisms, such as the Bald eagle, is dissipated at each level and none of it is recycled.

• matter from the Sun is recycled after many years by consumers, such as a Bachman's sparrow.

Why do higher trophic levels in most ecosystems contain fewer organisms than lower trophic levels?

• Energy available for use to the highest trophic level is small

• Energy available for use to the lowest trophic level is small.

• Energy available for use to the highest trophic level is large.

• Energy available for use to the highest and lowest trophic levels is the same.

Which of the following statements is most likely correct?

• The amount of energy is identical in each level of the pyramid.

• The amount of energy increases at each successive level from D to A.

Which of the following best describes how the chemical energy travels up the food pyramid?

• Chemical energy is used by each of the organisms in the food pyramid, resulting in less energy as it moves up the pyramid.

• Chemical energy is made by each of the organisms in the food pyramid, resulting in more energy as it moves up the pyramid.

• Chemical energy is not needed by the organisms in the food pyramid, resulting in equal amounts of energy throughout the food pyramid.

• Chemical energy is used by producers but created by consumers, resulting in fluctuations in the amounts of energy throughout the food pyramid.
