Nitrogen required to build proteinsNitrogen is part of bases that make amino acids
78% of atmosphere is Nitrogen
Most organisms cannot use nitrogen gas directly
Plants take in nitrogen in the form of nitrate ions
Ammonification
Ammonification- production of ammonia when saprobiotic organisms feed on dead organims releases ammonia which form ammonium ions
Nitrification- production of nitrite ions from ammonium.Carried out by nitrifying bacteria
Dentrification conversion of nitrate ions back to gas nitrogen by dentrifying bacteria
Nitrogen Fixation- conversion of nitrogen gas into nitrate ions. Carried out by 2 types of bacteria
Free living N.F.B- gas to ammonia
Mutualistic N.F.B- create a symbiotic relationship with plant living on nodules of roots. They take carbs from plants and in return give the plant amino acids for growth
