Answer 1

• Nitrogen compounds are of vital importance to plants.
• Nitrogen is an important constituent of proteins that are necessary for the growth of plants and animals.
• Plants cannot use the nitrogen which is present in the atmosphere and hence plants convert atmospheric nitrogen into usable compounds.

Therefore, the process of conversion of free atmospheric nitrogen into usable compounds is called nitrogen fixation.
