Draw a labelled diagram of nitrogen cycle

The nitrogen cycle is a biogeochemical cycle in which nitrogen is converted into multiple forms. It is a continuous or an endless cycle which helps us understand how nitrogen moves from the atmosphere to earth, through soils and back to the atmosphere. Nitrogen cycle has four major events-. Nitrogen fixation. First of all nitrogen-fixing microorganisms capture atmospheric nitrogen by converting it to ammonia NH 3 which can be taken up by plants and used to make organic molecules. Now, the nitrogen-containing molecules are passed to animals when they eat plants. They may be embodied in the animal's body or broken down and excreted as waste, such as the urea found in urine.

The series of processes by which nitrogen and its different forms are circulated and interconverted in nature with the help of living organisms is called the nitrogen cycle. It shows the path that nitrogen follows through the biogeochemical cycle using its storage reservoirs, such as the atmosphere, living organisms, and soil. The entire process of the Nitrogen Cycle, one of the important biogeochemical cycle takes place in five stages:. Nitrogen fixation — Performed by two different groups of bacteria — a symbiotic nitrogen fixers like Rhizobium, which keep a close association with the host leguminous plant, and b free-living, non-symbiotic bacteria like Azotobacter. Both these group of bacteria use specific enzymes to complete the biological nitrogen fixation process by the following reaction —. Plants help in the assimilation of nitrogen when they absorb it from the soil in the form of ammonia, nitrite ions, nitrate ions or ammonium ions to form plant and animal proteins. In leguminous plants such as pea and bean, the symbiotic association with Rhizobium helps to assimilate nitrogen directly in the form of ammonium ions. Denitrifiers such as Clostridium and Pseudomonas helps in the reduction ofnitrates NO 3 or nitrites NO 2 , resulting in the escape of gaseous nitrogen which again returns to the cycle. Lightning with thunderstorm serves as an important source of fixing nitrogen in the atmosphere apart from bacteria mediated nitrogen fixation. Here the energy of lightning breaks atmospheric nitrogen into nitrogen oxides which can then be utilized by plants for assimilation.

Nitrogen is the building block of protein and nucleic acids. It is an integral part of all life forms. Nitrogen is abundant in the atmosphere. For it to be used in various biological processes, it needs to be converted from inert atmospheric molecule to a useful form.
