Detailed explanation-1: -Denitrification by bacteria converts nitrates (NO3−) to nitrogen gas (N2). Nitrification by bacteria converts nitrates (NO3−) to nitrites (NO2−). Nitrogen fixing bacteria convert nitrogen gas (N2) into organic compounds.

Detailed explanation-2: -Denitrifying bacteria converts nitrates back to nitrogen gas.

Detailed explanation-3: -Denitrification. Denitrification is the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere. Dinitrogen gas (N2) is the ultimate end product of denitrification, but other intermediate gaseous forms of nitrogen exist (Figure 7).

Detailed explanation-4: -Denitrification-The process of conversion of nitrates into free molecular nitrogen by the action of bacteria (Pseudomonas) is called denitrification. Pseudomonas is a family of bacteria that converts nitrates into free nitrogen.
