|
Nitrogen gas returns to the atmosphere by the action of
|
|
nitrogen fixing bacteria.
|
|
|
denitrifying bacteria.
|
|
|
nitrifying bacteria.
|
|
|
ammonia.
|
Explanation:
Detailed explanation-1: -Denitrification. Denitrification is the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere.
Detailed explanation-2: -The action of denitrifying bacteria results in the formation of atmospheric nitrogen.
Detailed explanation-3: -denitrifying bacteria, microorganisms whose action results in the conversion of nitrates in soil to free atmospheric nitrogen, thus depleting soil fertility and reducing agricultural productivity.
Detailed explanation-4: -Denitrifying bacteria, conversely, reduce nitrate into gaseous nitrous and nitric oxides, and nitrogen gasses, which are volatilized to the atmosphere.
