Answer:
hope it helps.........
Explanation:
Nitrogen is essential nutrient for the survival of living being is found in protein like DNA and RNA. Nitrogen cannot be used directly from the atmosphere and have to be converted into nitrates and nitrites by certain nitrogen fixing bacteria. These bacteria are found in root noodles of leguminous, plant that give us pulses.
Another method through which the nitrogen in our environment can be converted into nitrates or nitrites is physical process of lightning the high pressure and temperature during the lightning create the nitrogen into oxide and nitrogen into oxide of nitrogen then dissolve in water bodies, thus forming nitrous and nitric acid.
Once nitrogen is converted to the useful form of nitrates and nitrites they can be used for the plant for use them to produce amino acids, which are then used to make protein other Complex compounds that requires nitrogen are also made of these through some Complex bio chemical process. These proteins by animal once these plants and animal die and and ded buried in the soil bacteria convert this protein back to nitrites and nitrates. The certain kind of bacteria converts protein to elemental nitrogen. Thus completing a complete nitrogen cycle.
