Detailed explanation-1: -Nitrification is the process that converts ammonia to nitrite and then to nitrate and is another important step in the global nitrogen cycle. Most nitrification occurs aerobically and is carried out exclusively by prokaryotes.

Detailed explanation-2: -Denitrification. Denitrification is the process in which heterotrophic and autotrophic bacteria convert nitrates into nitrites and then to nitrogen gas.

Detailed explanation-3: -The process of conversion of ammonia or reduced nitrogen compounds into the easily absorbable form of nitrogen that is nitrates and nitrites. It is an aerobic process. Chemoautotrophic bacteria play a major role in this process.

Detailed explanation-4: -Nitrate is then converted into ammonia by process of denitrification. The process of converting ammonia into nitrite is called as nitrification. The process of converting nitrogen into ammonia is called as ammonification.

Detailed explanation-5: -Nitrification is the process of converting ammonia to nitrates and nitrates to nitrites by oxidation reactions.
