Question

what does a pyramid of energy represent? the lifespan of organisms at each trophic level the number of organisms at each trophic level the amount of energy at each trophic level

Explanation:

A pyramid of energy is a graphical representation in ecology that shows the amount of energy available at each trophic level in an ecosystem. The lifespan of organisms is not represented by an energy pyramid, and the number of organisms is represented by a pyramid of numbers, not energy. So the correct option is the one about the amount of energy at each trophic level.

Answer:

the amount of energy at each trophic level (the third option: "the amount of energy at each trophic level")
