Front

Which organism has the most energy in a food web?

Back

Producers, such as plants (e.g., flowers), have the most energy in a food web.

Front

Which organism has the least energy in a food web?

Back

Top predators, such as owls, have the least energy in a food web.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how an organism obtains its energy.
