Answer 1

Ans. B

Sol. Bio-fertilizers convert nitrogen to

ammonia.

• Nitrogen fixation is a process by which

nitrogen in the Earth's atmosphere is

converted into ammonia (NH3) or other

molecules available to living organisms.

• Atmospheric nitrogen or molecular di

nitrogen (N2) is relatively inert: it does

not easily react with other chemicals to

form new compounds.

• Nitrogen fixation is carried out naturally

in the soil by nitrogen-fixing bacteria such

as Azotobacter.
