Detailed explanation-1: -A wide range of soil fungi and bacteria, called the decomposers, carry out the ammonification process. The decomposers consume the organic matter, and the nitrogen contained in the dead organism is converted to ammonium ions. The ammonium is then converted to nitrates by the nitrifying bacteria.

Detailed explanation-2: -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-3: -In marine ecology, ammonification is also referred to as ammonium regeneration and ammonium recycling. The term “nitrate ammonification” is sometimes used to refer to the dissimilatory reduction of nitrate to ammonium (e.g., Rysgaard et al., 1996).

Detailed explanation-4: -The source of ammonia is the decomposition of dead organic matter by bacteria called decomposers, which produce ammonium ions (NH4+). In well-oxygenated soil, these ions are then oxygenated first by nitrifying bacteria into nitrite (NO2-) and then into nitrate (NO3-).

Detailed explanation-5: -Ammonification:-It is the conversion of dead organic matter into ammonia. It is mostly performed by fungi and some nitrogen fixing bacteria. Denitrification-It is the conversion of nitrates into atmospheric nitrogen. It is performed by pseudomonas.
