take in carbon by eating other organisms

release carbon through respiration as carbon dioxide

convert the light energy to chemical energy

break down other organisms which releses atoms that other organisms use

release carbon dioxide through cellular respiration

Decomposers remove poisonous materials from dead organisms.

Decomposers release carbon atoms so that other organisms can use them.
