|
|
Conversion of N2 to N
|
|
|
Conversion of N2 to urea
|

All of the above

Explanation:
Detailed explanation-1: -Nitrogen fixation is the process by which gaseous nitrogen (N2) is converted to ammonia (NH3 or NH4+) via biological fixation or nitrate (NO3-) through high-energy physical processes. N2 is extremely stable and a great deal of energy is required to break the bonds that join the two N atoms.
Detailed explanation-2: -Nitrogen fixation is the process whereby molecular N2 gas is converted to reactive, biologically available forms of nitrogen.
Detailed explanation-3: -Ammonification is the process of conversion of organic nitrogen into ammonium ions with the help of bacteria and fungi. In the nitrogen cycle all the ammonium ions and ammonia are converted to nitrates in a process called nitrification.
