Question
What is the conversion of nitrates to nitrogen called as?
- Nitrification
- Ammonification
- Nitrogenous fixation
- Denitrification
Hint:
Denitrification is the microbial process of reducing nitrate and nitrite to gaseous forms of nitrogen, principally nitrous oxide (N2O) and nitrogen (N2). A large range of microorganisms can denitrify.
The correct answer is: 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.
- Denitrification is a response to changes in the oxygen (O2) concentration of their immediate environment.
