Detailed explanation-1: -Ammonification is the process where microscopic organisms like bacteria or other types of decomposing organisms, break down nitrogen-containing chemicals from dead organic matter, into simple substances like ammonia.

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: -The process of organic matter decomposition includes the physical breakdown of substrate and the biochemical transformation of complex organic molecules into simpler organic and inorganic molecules (Chapin et al., 2011).

Detailed explanation-4: -Ammonia. 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: -Decomposition of organic nitrogen of dead plants and animals in ammonia is called ammonification.
