Question

what is nitrogen fixation...​

Answer 1

Answer:

• Nitrogen fixation is the incorporation of atmospheric nitrogen into ammonia by various bacteria, catalysed by nitrogenase. This is an essential stage in the nitrogen cycle and is the ultimate source of all nitrogen in living organisms.

Answer 2

nitrogen fixation is a biological process in 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.
