73.) 'In the absence of microorganisms the earth would become a heap of deadplants and animals.' Justify this statement.

Answer»

Decomposes play a very important role , all living beings including plants ,animals and their products if not decomposed after death would form heaps on the surface of the earth and would pose a threat to us and our crops , we shall not be left with any place to live in a few years .It is de composers which decompose all organic waists which then again forms a part of the soil thus it makes space for us , our crops and cattle on one hand and maintains fertility of soil on the other hand .

This is because microorganisms helps the dead and decayed plants and animals to decompose and if they would not be there they the dead and decayed plants and animals would not be decomposed..

this is because microorganisms helps the dead and plant to decompose
