The role of bacteria in the Nitrogen Cycle is to perform biological nitrogen fixation. This process is an important part of the Nitrogen Cycle because it converts oxygen into ammonia that plants are then able to use.
Assimilation
By the process denitrification. Some bacteria do that also human
The organisms that are involved in the movement of nitrogen between the air and soil and back to the air are plants and bacteria. When plants decompose they release nitrogen and bacteria fixes nitrogen back into the air.
Nitrifying bacteria can convert atmospheric nitrogen in to nitrates that plants can use in the soil. That is why leguminous plants having these micro-organisms in the nodules enrich the soil for nitrogen deficiency.
denitrification
Legumes fix nitrogen in the soil.
Bacteria in the soil called nitrogen-fixing bacteria go through a process called nitrogen-fixation which allows nitrogen to enter the atmosphere
When organisms die, decomposers return nitrogen to the soil as ammonia. The ammonia may be taken up again by producers. Other soil bacteria convert nitrates into nitrogen gas in a process called denitrifrication. this process releases nitrogen into the atmosphere once again.
denitrification is soil bacteria converting nitrates into nitrogen gas, is process releases nitrogen into the atmosphere. If there wasn't any bacteria, there would be no process and therefor the nitrogen wouldn't make it into the atmosphere.

The organisms that are involved in the movement of nitrogen between the air and soil and back to the air are plants and bacteria. When plants decompose they release nitrogen and bacteria fixes nitrogen back into the air.
When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use. Other types of bacteria are able to change nitrogen dissolved in waterways into a form that allows it to return to the atmosphere.
Denitrofying bacteria help to metabolize nitrogen so that they can use the it. These bacteria take available nitrogen from the soil, as opposed to nitrifying bacteria that increase available nitrogen in the soil.
algae help return nitrogen to te soil?
Nitrifying bacteria can convert atmospheric nitrogen in to nitrates that plants can use in the soil. That is why leguminous plants having these micro-organisms in the nodules enrich the soil for nitrogen deficiency.
Nitrogen fixation is one process by which molecular nitrogen is reduced to form ammonia. This complex process is carried out by nitrogen-fixing bacteria present in the soil.
when nitrogen go from soil to back in atmosphere due to nitrogen fixing bacteria then it again return to soil due to lightning, dead animals, roots of plants and by other ways. and again go to atmosphere in this way nitrogen cycled.
