e) Ammonification is part of the five-step nitrogen cycle, which is crucial for providing living organisms with the essential nitrogen that they need. Ammonification itself takes place thanks to the existence of decomposers, which break down animal and plant cells into simpler substances, making nutrients available in the ecosystem. The process of ammonification converts organic nitrogen, which is the way nitrogen is contained in compounds in living organisms, into inorganic ammonia (NH3) or ammonium ions (NH4+). Some examples of nitrogen-containing compounds in us and in other living organisms are proteins, nucleic acids like our DNA, vitamins like B-vitamins, and urea. The decomposers in this case are different bacteria and fungi that feed on these compounds, releasing ammonia, which in turn forms ammonium compounds in the soil to be taken up by plants.
