Front

What are consumers?

Back

Consumers are organisms that cannot make their own food and must eat other organisms for energy.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.
