Refer to the illustration above. the diagram, which shows how energy moves through an ecosystem, is known as a
a. habitat.
c. food net.
b. food chain.
d. food web.

While you did not show a diagram, I can safely say that the correct answer in this case is the food chain. The food chain is often depicted by a diagram that shows how energy moves through an ecosystem through different organisms of a certain ecosystem contributing their energy to it as well as how they use the energy from the same ecosystem.
