They convert complex organic molecules present in dead and decay matter into simple inorganic molecules and allow them to mix with the soil. Thus, they help to recycle nutrients. They clean the forest decaying dead bodies and replenish the nutrients back to the forest soil.
Some decomposers are bacteria, fungi, beetles and grubs.
