NURSING ANM AND GNM

Detailed explanation-1: -Ammonification. When an organism excretes waste or dies, the nitrogen in its tissues is in the form of organic nitrogen (e.g. amino acids, DNA). Various fungi and prokaryotes then decompose the tissue and release inorganic nitrogen back into the ecosystem as ammonia in the process known as ammonification.

Detailed explanation-2: -Nitrification, as stated above, is formally a two-step process; in the first step ammonia is oxidized to nitrite, and in the second step nitrite is oxidized to nitrate. Different microbes are responsible for each step in the marine environment.

Detailed explanation-3: -The ammonia generated from nitrogen fixation is first converted into nitrates by Nitrosomonas and then converted into nitrate by Nitrobacter and the process is called nitrification.
