Question

What are three ways that nitrogen gas can be fixed in nature?

Answer 1

n the atmosphere, nitrogen is fixed (i.e. N2 is converted to NH3) in three ways:

(1) bacteria,

(2) by humans through a manufacturing process called Haber process used in fertilizer production, and

(3) through a chemical process initiated by lightning. Certain bacteria are diazotrophs (or more simply, nitrogen-fixers).

Answer 2

The process of conversion of free atmospheric nitrogen into useful nitrogen compounds is called $\textbf{nitrogen fixation. }$

The differnt ways by which nitrogen is being fixed in nature are :

1. By symbiotic bacteria like Rhizobium.

2. During lighting.

3. By using manures and fertilizers.
