Detailed explanation-1: -Solution: The micro-organisms which convert the dead plants and animals to humus are known as decomposers. Examples: Fungi and Bacteria. Decomposers recycle and convert the dead matter into humus which mixes with forest soil and provides necessary nutrients to plants.
Detailed explanation-2: -Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren’t in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
Detailed explanation-3: -Decomposers break down dead and decaying organic matter that includes fallen leaves, dead plant parts and animals. Thus is also called as detritus. They helps in soil replenishment by adding nutrients to the soil.
