Biology question, due tomorrow: What is an example of energy flow between trophic levels?

Question

I need a brief example, a paragraph or so. Thank you so much!

Answer 1

Herbivores eating plants, or carnivores eating herbivores.

In the first example, energy is transfer from one tropic level (plants) to the next trophic level (herbivores).  The same is true for the second example -- energy is transfer from one trophic level (herbivores) to another (carnivores).
