Question

What does a consumer in a food chain depend on for energy???

Answer 1

It sounds like you're talking about Producers, Consumers, and Decomposers. A consumer would be something that eats something else to survive (birds, humans), a producer makes its own food (trees, plants), and a decomposer eats dead things and turns them into soil (worms, slugs).

Answer 2

Are you asking about cellular energy? In which case ATP. ATP is ultimately generated by the sun. Thereby, all consumers in the food chain depend on the sun.
