Nitrogen gas forms 48% of air . It cannot be used as such by plant nd animal . it must be converted into biological acceptable forms . A number of free living bacteria ( Azobacter nd Clostridium ) Symbiotic bacteria Rhizobium nd blue green algae take up free atmospheric nitrogen nd convert it into ammonia that combines with organic acid to form amino acid . the latter r used to form protein . this process called biological fixation .
Nitrogen fixation is the process in which the atmospheric nitrogen is fixed by certain bacteria into ammonia.Nitrification is the process in the ammonia is oxidized into nitrite which is further oxidized nitrates.Both nitrogen fixation and nitrification are important parts of nitrogen cycle.
Organism involved in nitrogen fixation is :-
1) Rhizobium bacteria ( in root nodules of leguminous plants ).
2 ) Azotobacter in bacteria.
3) Blue green algae .
Organism involved in nitrification:-
1) Nitrosomonas bacteria .
2) Nitrobacter bacteria .
