Question

The following diagram shows a food web.



What can be concluded from the diagram?
A.
Plants can transform sunlight energy into chemical energy that animals can use.
B.
Plants and animals can both transform sunlight energy into chemical energy.
C.
Plants can obtain chemical energy from sunlight or from animals.
D.
Plants can provide chemical energy to the Sun and to animals.

Answer 1

A.

Plants (producers) use photosynthesis to convert sunlight into chemical energy in organic matter. That energy then flows to herbivores and higher-level consumers in the food web. The other choices are incorrect: animals generally do not convert sunlight to chemical energy, plants do not get chemical energy from animals, and plants cannot provide energy to the Sun.
