This picture shows a very simple and clear nitrogen cycle.
In the nitrogen cycle the Rhizobium bacteria which is present in the root nodules of leguminous plants fixes nitrogen in soil.
The same work is done by Cynobacteria or Blue- Green Algae
Also nitrogen is fixed in soil when a green plant or animal is died and after that it is eaten by bacteria.
So we can say that Bacteria is very important organism in the nitrogen cycle.
