|
None of the above

Detailed explanation-1: -Denitrification is the process in which the nitrogen compounds make their way back into the atmosphere by converting nitrate (NO3-) into gaseous nitrogen (N). This process of the nitrogen cycle is the final stage and occurs in the absence of oxygen.
Detailed explanation-2: -Denitrification is the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere.
Detailed explanation-3: -3) Denitrification is the process where the fixed nitrogen is further converted to free nitrogen.
Detailed explanation-4: -The positive implication is that denitrification converts nitrates (NO-) to nitrogen gas, resulting in a net loss of nitrate from the soil system. The negative aspect of denitrification is that it takes place in soils that are waterlogged.
Detailed explanation-5: -Denitrification. Denitrification completes the nitrogen cycle by converting nitrate (NO3-) back to gaseous nitrogen (N2). Denitrifying bacteria are the agents of this process. These bacteria use nitrate instead of oxygen when obtaining energy, releasing nitrogen gas to the atmosphere.
