WebNitrogen fixation is the process of converting molecular nitrogen (N 2, which makes up 78% of the atmosphere) into ammonia (NH 3, which is used by many organisms as a nitrogen source). With a few exceptions, only a limited number of prokaryotes are capable of nitrogen fixation, and they are distributed in a mosaic manner across at least 14 phyla … WebBacteria play a key role in the nitrogen cycle. Nitrogen enters the living world by way of bacteria and other single-celled prokaryotes, which convert atmospheric nitrogen— \text N_2 N2 —into biologically usable forms in a process called nitrogen fixation.
