Biochemical cycle | Nitrogen Cycle | Class 12 Biology About This Video ........................ In This Video Lecture You Will Learn Basic Concept Of Nitrogen Cycle. The chief reservoir of nitrogen is the atmosphere; in fact nitrogen makes up 78 percent atmospheric nitrogen to make amino acids and other nitrogen containing compounds, of ecosystem in a cyclic manner. of the gases in atmosphere. Since most living things, however, cannot use elemental trace amount like zinc, molybdenum, iron, iodine. The nutrient cycles are also called nitrogen in the atmosphere, shortage of nitrogen in the soil is often the major limiting amount like water, carbon, hydrogen, oxygen, nitrogen, phosphorus, sulphur and factor in plant growth. The process by which this limited amount of nitrogen is circulated and re-circulated throughout the world of living organisms is known as the nitrogen The chemical elements essential for life in living organisms are called biogenic elements they are dependent on nitrogen present in soil minerals. So, despite the abundance of or nutrient elements. Macronutrients are elements required by organisms in large calcium. Micronutrients are elements required by organisms in small quantity or in biogeochemical cycles as the nutrients move from living to nonliving to living portions cycle. Three principal stages of this cycle are, ammonification, nitrification, and acids, nucleic acids and nucleotides. These nitrogenous compounds are usually rapidly most nitrogen moves from the soil into the roots. Once nitrate is within the plant cell, it is reduced back to ammonium. In contrast to the nitrification, this assimilation materials and is in the form of complex organic compounds, such as proteins, amino ammonia (NH3 is known as nitrification. fungi. These microorganisms use the proteins and amino acids and release excess of ) or ammonium ions (NH4 Much of the nitrogen found in the soil is the result of the decomposition of organic Several bacteria in soil are able to oxidize ammonia or ammonium ions, this oxidation Although the plants can utilize ammonium directly, nitrate is the form in which ). This process is known as ammonification. process requires energy. The ammonium ions thus formed are transferred to carbon assimilation. decomposed into simple compounds by soil-dwelling organisms chiefly bacteria and + containing compounds to produce amino - acids and other nitrogenous organic compounds needed by the plant. About This Channel..................... I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources. One-stop destination for all biology lectures. _ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial _ The videos are categories under various heading to make the students life simplified Visit My Other Channel Playlist .....................
