The nitrogen cycle is a cyclic process that transforms nitrogen and nitrogen containing compounds in nature. Earth's atmosphere has ubout 78% of nitrogen gas. It forms essential constituents of all living organisms and is essential for many biological processes. It is present in all amino acid, proteins, nucleic acid and vitamins. In plants, nitrogen is a part of chlorophyll molocule. Fixation of nitrogen is an essential process as nitrogen cannot be directly taken by plants and animals, So it needs to be fixed and then converted into some usable compounds. Certain bacteria and some blue green algae are able to fix the nitrogen and assimilate it as organic nitrogen. An example of N, fixing bacteria is Rhizobium, This process is called biological fixation. Once the nitrogen is converted into usable form it is absorbed from the soil by the plant. Animals obtain this nitrogen directly or indirectly from the plants. When a plant or animal dies, nitrifying bacteria and some fungi present in the soil converts all the organic nitrogen into ammonia, nitrites and nitrates. Another type of tacteria then convert these nitrites and nitrates into elemental nitrogen which is then released into atmosphere, completing the
