Explanation:
Detailed explanation-1: -Nitrogen gas (N2) has two nitrogen atoms connected by a very strong triple bond. Most plants and animals cannot use the nitrogen in nitrogen gas because they cannot break that triple bond.
Detailed explanation-2: -Nitrogen is needed both by Plants and Animals because it is the major constituent of proteins, vitamins, hormones, etc. Nitrogen is a crucially important component of life. It is an abundant element present in the atmosphere.
Detailed explanation-3: -Nitrogen is a building block of all living organisms. Plants and animals cannot absorb nitrogen directly from the air. So they are oxidized into Nitrates and Nitrites by the process of nitrogen fixation and then they are absorbed by the plants.
