Question

What would happen if all the decomposers were eliminated from the Earth? Explain.

Accepted Answer

Decomposers are organisms that break down dead or decaying organisms and when doing so, they carry out the natural process of decomposition. They are also called as saprophytes. They secrete enzymes over the organic remains which causes break down of organic remains into simpler and soluble substances that are absorbed by them.

Bacteria and fungi are decomposers. They release minerals and other raw materials trapped in organic matter. A continued replenishment of these raw materials is essential for the growth of plants and hence maintenance of the ecosystem. They help in returning the various nutrient elements which were initially taken by the plants from the soil, air and water.

In the absence of decomposers, soil, air and water would not be replenished, and all the nutrients present would soon get exhausted. The dead and decayed matter will also accumulate to a large extent on the Earth. Hence, the cyclic process of life and death would be disrupted and life would come to an end.
