Answer:
The nitrogen cycle is one of the most important cycles through which nitrogens move from the environment into organisms and from organisms back into the environment.
Decomposers are an important part of this cycle as the cycle is maintained due to these organisms.
The nitrogen-fixing bacteria change nitrogen into a kind which can be broken and be used by other organisms.
The Ammonifying bacteria (decomposers) feed on dead, decay material and break down ammonium compounds and convert them to other nitrogenous compounds.
Nitrifying bacteria convert the ammonium compounds into nitrites and nitrates.
Denitrifying bacteria convert nitrates into nitrogen gas to release it back into the atmosphere.
