Nitrogen is an important element to all life on Earth. ; In reverse, denitrification converts nitrates back to N 2 as a gas. Nitrogen cycle definition, the continuous sequence of events by which atmospheric nitrogen and nitrogenous compounds in the soil are converted, as by nitrification and nitrogen fixation, into substances that can be utilized by green plants, the substances returning to the air and soil as a result of the decay of the plants and denitrification. The Nitrogen Cycle. Nitrogen fixing converts N 2 from the air into nitrates. In order to move through the different parts of the cycle, nitrogen must change forms. The nitrogen cycle describes how nitrogen moves between plants, animals, bacteria, the atmosphere (the air), and soil in the ground. Different Nitrogen States For Nitrogen to be used by different life forms on Earth, it must change into different states. There are four main types of bacteria involved in the Nitrogen Cycle: Decomposer bacteria – decomposes proteins and urea and turns them into ammonia. Unlike oxygen, nitrogen is not absorbed from the air by plants or animals. This nitrite is then converted to nitrate (non-toxic) with the help of the same cycle. Nitrogen is important to anything that is living on the Earth. To put it simply, the nitrogen cycle establishes beneficial bacteria in your tank that helps in filtering media and creating a safe environment for your aquatic pets. This is done in a two-step process: Once established, beneficial bacteria will begin converting ammonia into less harmful nitrites . The nitrogen cycle is a process of establishing colonies of beneficial bacteria which will dissolve toxic compounds into less toxic (or completely harmless ones). The nitrogen cycle is how nitrogen moves through the atmosphere. The nitrogen cycle uses different things to move the nitrogen around. Nitrogen is important to all life. The nitrogen cycle is a repeating cycle of processes during which nitrogen moves through both living and non-living things: the atmosphere, soil, water, plants, animals and bacteria. Nitrogen in the atmosphere or in the soil can go through many complex chemical and biological changes, be combined into living and non-living material, and return back to the soil or air in a continuing cycle. Nitrification is the process that converts ammonia to nitrite and then to nitrate and is another important step in the global 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 helps convert ammonia to nitrite, which is also toxic by nature. The nitrogen cycle consists of 4 major steps. The nitrogen cycle is a series of different processes that take place to make nitrates and ammonium to be used and then, at times, returned back to the cycle to be used again. ; Finally, nitrification converts ammonia into nitrates.
