Detailed explanation-1: -Nitrogen is essential for all living things because it is a major part of amino acids. Amino acids are the building blocks of proteins that form enzymes which carry out various enzymatic reactions.
Detailed explanation-2: -Nitrogen plays an important role in animal production because it is essential for the production of animal tissue, milk, eggs and wool. Grasses provide more than 70% of the global protein intake by animals. Two-thirds of the remaining protein is supplied by feedstuffs and one-third by products like kitchen wastes.
Detailed explanation-3: -Most animals source their nitrogen requirements from food. Carnivorous animals get their nitrogen from the protein in the meat they consume. In contrast, herbivores get it from plant materials strong in protein or amino acids, such as leguminous plants.
