Chapter 28.1, Problem 2.1CC
Summary Introduction
The growth or development of all the living organisms depends upon the obtainability of mineral nutrients. Nitrogen is a mineral and also a crucial constituent of the bodies of all the living organisms as the nitrogen atoms are present in DNA and all proteins. In the atmosphere, nitrogen exists as nitrogen (N2) gas. During nitrogen fixation, bacteria transform N2 into ammonia. Ammonia is a form of nitrogen, which can be readily used by plants.

Students have asked these similar questions
Regarding nitrogen fixation, are the following statements True or False?
a) Atmospheric nitrogen is reduced to the biologically useful form NH3 (or NH4 ).
b) Nitrogen fixation in nature and in the lab requires a metal cofactor or catalyst.
c) The availability of fixed nitrogen limits biological productivity.
d) Ammonium from the atmosphere is fixed to more usable forms of nitrogen, such as nitrite (NO2–).
e) Nitrogen fixation is energetically neutral, using a negligible amount of ATP.
f) The enzyme nitrogenase, which takes part in nitrogen fixation, is inactivated by oxygen.
