In the absence of decomposers, soil, air, and water would not be replenished, and all the nutrients present would soon get exhausted. Hence, the cyclic process of life and death would be disrupted and life would come to an end.
Some examples of decomposers include bacteria, fungi, and some insects. If decomposers disappeared from a forest ecosystem, wastes as well as the remains of the dead organisms would pile up, and producers (plants) would not have enough nutrients.
If decomposes were absent of the forest system, nitrogen wouldn’t be able to return to the atmosphere from animal bodies and the corpses of animals would be lying around and rotting away instead of properly decomposing.
Hope this helps in any way!
