Answer 2

Answer:

Explanation:

Nitrogen fixation is of two types

                                  1) biological nitrogen fixation

                                  2) physical nitrogen fixation

1) Biological nitrogen fixation:- Biological nitrogen fixation (BNF), is carried out by a specialized group of prokaryotes. These organisms utilize the enzyme nitrogenase to catalyze the conversion of atmospheric nitrogen (N2) to ammonia (NH3).

2) physical nitrogen fixation:-

nitrogen fixation, any natural or industrial process that causes free nitrogen (N2), which is a relatively inert gas plentiful in air, to combine chemically with other elements to form more-reactive nitrogen compounds such as ammonia, nitrates, or nitrites
