One of the only decomposers that is able to survive in the desert is bacteria because they are tiny and can survive in the air. Other decomposers, such as millipedes, earth worms and beetles, also live in the desert, but they have a difficult time surviving because they depend on moist areas.
The role of decomposers in nature is to recycle dead matter, which helps to keep nutrients flowing. Because of their small size, decomposers are capable of breaking down portions of dead plants and animals. The job that decomposers perform helps to ensure that the ground is not topped with junk. This is crucial in maintaining nature's balance.
