Nitrification reactions carried out be bacteria as part of the nitrogen cycle cn be considered is D. nitrogen fixation.
Nitrification reactions carried out by bacteria as part of the nitrogen cycle can be considered as nitrogen fixation.
Nitrogen fixation is the 1st step of nitrogen cycle, where atmospheric nitrogen is converted to ammonia whereas Nitrification is the 2nd step that involves conversion of ammonia to nitrates and nitrates.
Specialized bacteria oxidize ammonium to nitrite and eventually to nitrate through the aerobic microbial process known as nitrification. Since nitrate is the most favoured chemical form of nitrogen absorption from soil or water for the majority of plants, nitrification is a crucial component in the nitrogen cycle.
The process of nitrification involves turning ammonia into nitrites (NO 2 -) and eventually nitrates (NO 3 -). Specialized microorganisms do this function in the environment on a natural basis. Ammonia is created when organic nitrogen sources break down.
