Question

what is nitrogen fixation​

Answer 1

Nitrogen fixation is the process by which nitrogen is taken from its stable gas form (N2) in air and changes into other nitrogen compounds (such as ammonia, nitrate and nitrogen dioxide) useful for other chemical processes. It is an important part of the nitrogen cycle.
