Dear Chegg, I need help with following environmental chemistry / earth science oral exam question in detail and hope that someone can help me, so I can prepare myself extra good for the exam:5. Explain the natural nitrogen cycle and the anthropogenic changes to the nitrogen cycle. (In detail!)
(Anything like reaction schemes, references and everything that's good and can be shown at the exam.. I would love to have them and therefore I hope someone can include it to the answer down below) Dear Chegg, I need help with following environmental chemistry / earth science oral exam question in detail and hope that someone can help me, so I can prepare myself extra good for the exam:

Explanation / Answer
Answer:
The nitrogen cycle is a natural biogeochemical cycle which include interaction among the land, water and atmosphere, by the processes like fixation, ammonification, nitrification, and denitrification. These process are divided on the basis of their environment and reactions.
Fixation starts on the surface of land by absorbing the nitrogen from bacteria which living on the land and fix in the roots of plants or tress.
Ammonification starts after the death of plants via bacteria, when these plants waste dispose in the land then fixed nitrogen int the form of organic niogen transform into ammonium.
Nitrification includes the conversion of ammonium into nitrate via bacteria.
Denitrification consists finally the transformation of nitrates into nitrogen gas which turns back into atmosphere.
Anthropogenic activities may disturb the nitrogen cycle by using more fertilizers, pesticides or chemicals which includes nitrogen.
