The comammox bacteria play a role in nitrification and thereforein the nitrogen cycle. Other microbes, with distinct ecologicalniches, also participate in the nitrogen cycle. The metabolicreactions involving nitrogen that bacteria perform include:nitrogen fixation (N2 → NH3), nitrification(NH3 → NO3- orNO2-), and denitrification(NO3- or NO2- → NO,N2O, and N2), all of which make up thenitrogen cycle. Each of these reactions is carried out by a uniqueset of microorganisms with a distinct ecological niche.
