The conversion of ____________ is called nitrogen fixation.
- N2 to NH3
- N2 to urea
- N2 to N
- N2 to NO3-
Hint:
Nitrogen fixation is the process, in which nitrogen gas present in the atmosphere is converted into ammonia and other related nitrogenous compounds.
The correct answer is: N2 to NH3
- Nitrogen Fixation is a biological process in which nitrogen gas is converted into a usable form for plants and other microbes.
- In this process, nitrogen gas present in the atmosphere is converted into ammonia and other related nitrogenous compounds.
- The molecular nitrogen, with a strong triple covalent bond, in the air is converted into ammonia or related nitrogenous compounds, typically in soil or aquatic systems but also in industry.
