What role do plants play in an ecosystem?

Back

Plants are primary producers that convert sunlight into energy through photosynthesis.

Front

Explain the concept of energy transfer in an ecosystem.

Back

Energy transfer in an ecosystem occurs when one organism eats another, passing energy from one trophic level to the next.

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.
