Front

What is a food pyramid?

Back

A food pyramid is a graphical representation of the energy flow in an ecosystem, showing the hierarchy of trophic levels.

What role do decomposers play in a food web?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.
