Question

The conversion of ____________ is called nitrogen fixation.

  1. N2 to NH3
  2. N2 to urea
  3. N2 to N
  4. N2 to NO3-

hintHint:

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.
