Explain nitrogen cycle formation

1.	Explain nitrogen cycle formation
Answer» Nitrogen cycle - the nitrogen in atmosphere in N2 firm get converted into its oxides NO3 &NO3 ( NITROGEN FIXATION) by industries ,some bacteria ( rizobium , azatobactor)and by lightning .The NO2 AND NO3 are absorbed by plants and makes many nitrogenous compounds (proteins , amino acids etc) these compounds goes to animals when they eat it and it comes out when they excreate. In soil, bacteria converts this NO2 AND NO3 into ammonia(NH4) (AMMONIFICATION) this ammonia tends to N2 FIXATION BY SOME BACTERIAS and by DENITRIFIACTION NO2 AND NO3 GET converted into N2 again
