What fixes nitrogen in the atmosphere
Blababa [14]
<h2>Nitrogen fixation </h2>

Explanation:

It is the process of converting free nitrogen into nitrogenous compounds .

Let us study about it :

In nature there are certain plants called as leguminous plants .These plants have nitrogen fixing bacteria called as rhizobium  in their root nodules .

This bacteria can convert free atmospheric nitrogen into ammonia .

Then this ammonia with the help of bacteria nitrosomonas and nitrobacter gets converted into  nitrites and nitrates .

Then these nitrites and  nitrates with the help of bacteria like pseudomonas gets converted back into free nitrogen ,

This cycle helps in enriching the soil and to maintain nitrogen percent constant in atmosphere ,

The biogeochemical cycle : for nitrogen is attached below
