How is the nitrogen cycle important to humans

Explanation:

Nitrogen cycle is one of the important biochemical cycle in nature. The element nitrogen is fixed by the soil bacteria which is available in nature in the form of atmospheric nitrogen. The atmospheric nitrogen is absorbed by the soil bacteria which converts it into forms like nitrates and nitrites which are easily absorbed by the plants. The plants use these forms for the synthesis of amino acids. These amino acids are used by the plants to synthesize their proteins.

The plants and their products are the source of proteins which are the building blocks of human body. The proteins are necessary for building up the muscle mass, renew of hair and skin, repair of injured tissues, defense against the injury, foetal development and others. Hence, nitrogen cycle is important for humans.
