What is the Process for Converting Atmospheric Nitrogen into Ammonium

Question

What is the process for converting atmospheric nitrogen into ammonium?
A) nitrogen absorption
B) nitrogen fixation
C) nitrogen conversion
D) nitrogen cycling

Accepted Answer

Nitrogen fixation is the process through which atmospheric nitrogen (N2) is converted into ammonium (NH4+), making it available for use by plants and other organisms. This can be carried out by certain bacteria and archaea, either free-living or in symbiotic relationships with plants.
