What are producer consumer and decomposers?

Producers are organisms that can create their own food from raw chemicals and energy from sunlight. (Plants)

Consumers are organisms that can't make their own food so they kill and eat other living things to live. (Cows and Tigers)

Decomposers are organisms that eat the stuff that consumers leave behind, they rot things away and release the chemicals for producers to re use. (Mushrooms and bacteria).
