However, the abundant nitrogen in the atmosphere cannot be used directly by plants or animals. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms.Biological nitrogen fixation converts N 2 into ammonia, which is metabolized by most organisms. The nitrogen bases are also called nucleobases because they play a major role as building blocks of the nucleic acids deoxyribonucleic acid and ribonucleic acid (). Start studying Biology- Nitrogen. A nitrogenous base is an organic molecule that contains the element nitrogen and acts as a base in chemical reactions. Learn more. Start studying Biology ( Nitrogen Cycle).

The term legume has two closely related meanings in botany, legume can refer to either the plant itself, or to the edible fruit (or useful part). Nitrogen is essential for all living things because it is a major part of amino acids, which are the building blocks of proteins and of nucleic acids such as DNA, which transfers genetic information to subsequent generations of organisms. Nitrogen compounds have a very long history, ammonium chloride having been known to Herodotus.They were well known by the Middle Ages. Although nitrogen is abundant in the atmosphere, most organisms cannot use it in that form. Nitrogen fixation is a process by which molecular nitrogen in the air is converted into ammonia (NH 3) or related nitrogenous compounds in soil. Denitrification is the last step in the nitrogen cycle where the reduction of soil nitrate to nitrogen-containing gases, such as nitric oxide, nitrous oxide, and nitrogen gas, takes place. The basic property derives from the lone electron pair on the nitrogen atom. Nitrogen Cycle Definition: The nitrogen cycle can be defined as one of the biogeochemical cycles that converts the unusable inert nitrogen existing in the atmosphere into a more usable form of nitrogen for living organisms. There are four main types of bacteria involved in the Nitrogen Cycle: Decomposer bacteria – decomposes proteins and urea and turns them into ammonia. Nitrogen-fixing bacteria accomplish more than 90 percent of all nitrogen fixation and thus play an important role in the nitrogen … Nitrogen is a component of proteins and nucleic acids and is essential to life on Earth. Nitrogen Cycle Definition “Nitrogen Cycle is a biogeochemical process which transforms the inert nitrogen present in the atmosphere to a more usable form for living organisms.” Furthermore, nitrogen is a key nutrient element for plants. nitrogen meaning: 1. a chemical element that is a gas with no colour or taste, forms most of the earth's atmosphere…. Alchemists knew nitric acid as aqua fortis (strong water), as well as other nitrogen compounds such as ammonium salts and nitrate salts. The Nitrogen Cycle The Nitrogen Cycle: A sequence of processes by which nitrogen moves from the atmosphere through living and dead organisms, into the soil and back to the atmosphere. Nitrogen cycle definition is - a continuous series of natural processes by which nitrogen passes successively from air to soil to organisms and back to air or soil involving principally nitrogen fixation, nitrification, decay, and denitrification.
