Question
The conversion of atmospheric nitrogen to nitrogenous compounds is called: A. Ammonification B. Nitrification C. Nitrogen fixation D. Denitrification
Correct Answer
Option C is the correct answer.
Detailed Explanation
Nitrogen fixation is the process by which inert atmospheric nitrogen gas (N2) is converted into biologically useful nitrogenous compounds, such as ammonia (NH3) or nitrates (NO3-). This can be done by bacteria, or by lightning.
Hint
This process 'fixes' the unusable nitrogen gas into a form organisms can use.
