• ​Producers (also called autotrophs) make their own food.

• Many like plants and algae use photosynthesis and convert energy from the sun into sugars.

• Producers without access to sunlight make energy molecules using chemicals in their environment using chemosynthesis.

Consumers eat other organisms for energy.

​Many fungi like mushrooms are decomposers, along with different insects and bacteria.
