Dear student, Nitrogen cycle is the biogeochemical cycle that describes the transformation of nitrogen and nitrogen-containing compounds in nature. Atmospheric nitrogen is the biggest source of nitrogen. Green plants absorb nitrogen in the form of nitrates and nitrites from the soil and water. Animals get nitrogen when they feed upon plants. Nitrogen is an essential component of proteins and nucleic acids in living organisms. The nitrogen cycle can be studied in five steps: i. Nitrogen fixation : Free living micro-organisms present in the soil and by the symbiotic bacteria in the root nodules of certain leguminous plants: Microbes like the blue green algae and bacteria fix the atmospheric nitrogen into nitrites and nitrates. These nitrogenous compounds are then released into the soil.

Draw a neat and well labelled diagram of Standard Hydrogen Electrode. The nitrogen cycle can be studied in five steps: i. Lightning is a curseforce phenomenon which occurs in the sky and responsible for nitrogen fixation.

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 nitrogen cycle is a biogeochemical cycle that converts nitrogen into various forms throughout the ecosystem. Nitrogen is an essential element for life that organisms use in the synthesis of amino acids , proteins , and nucleic acids. Through the nitrogen cycle, atmospheric nitrogen undergoes various transformations. Living organisms use nitrogen and ultimately return it back to the atmosphere. Several processes play a role in the nitrogen cycle, including both biotic living and abiotic non-living factors. These processes include nitrogen fixation, assimilation, ammonification, nitrification, and denitrification. Nitrogen fixation is the initial step of the nitrogen cycle, converting inert atmospheric nitrogen N 2 into a bio-available form, ammonia NH 3.

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.
