Question

The process of conversion of molecular nitrogen to ammonia or nitrogen oxides is known as ___.

• A. nitrogen fixation
• B. nitrogen formation
• C. nitrogen distillation
• D. nitrogen conversion

Answer 1

The correct option is A nitrogen fixation

Nitrogen fixation is the process by which the nitrogen present in the environment is converted into ammonia $\left(N{H}_3\right)$ or other nitrogenous compounds.

This is really important because plants and other organisms present in the soil can't directly use the atmospheric nitrogen $\left(N_2\right)$. The fixation process converts nitrogen $\left(N_2\right)$ into ammonia, which can then be metabolized by most of the organisms.
