Answer 1

Solution:

It is the bacteria which are used to break down the molecules of nitrogen into necessary components that are used further by other living beings.

In the nitrogen cycle, nitrogen is mainly converted into other forms on account of bacterial action.

The entire process of converting nitrogen into other components is called nitrification.
