Question

Name the process of conversion of free atmospheric nitrogen into usable compounds.

Answer 1

• Nitrogen compounds are of vital importance for plants.
• Nitrogen is an important constituent of proteins that are necessary for the growth of plants and animals.
• Plants cannot use nitrogen which is available in the atmosphere and hence they convert free atmospheric nitrogen into usable compounds by a process called nitrogen fixation.

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