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 Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. The majority (78%) of the Earth’s atmosphere is N2. The Nitrogen Cycle Nitrogen (N) is an essential component of DNA, RNA, and proteins, the building blocks of life. During the first step, nitrogen fixation, special bacteria convert nitrogen gas into ammonia which is used by plants. However, the cycle works differently in the enclosed environment of the aquarium. Process of Nitrogen Cycle consists of the following steps – Nitrogen fixation, Nitrification, Assimilation, Ammonification and Denitrification. The uniqueness of the nitrogen cycle is that nitrogen is the most abundant gas in the earth’s atmosphere, about 78% of all air, but it can’t be directly utilized by the animals and plants unless it is converted into usable compounds. Nitrification is a process that converts ammonia into nitrate by bacteria. A special enzyme known as dinitrogenase is responsible for the fixation process. It is a cycle within the biosphere which involves the atmosphere, hydrosphere, and lithosphere. The reaction involved in the process of Nitrification is as follows: Primary producers – plants take in the nitrogen compounds from the soil with the help of their roots, which are available in the form of ammonia, nitrite ions, nitrate ions or ammonium ions and are used in the formation of the plant and animal proteins. 9/25/2013 1 2.

These changes to different nitrogen oxides are dependent on various activities of microorganisms such as bacteria and fungi. About. (And Which Foods Do They Actually Like), How Do Birds Mate? In the process of ammonification, the bacteria help in decomposing the animal and plant matter, which indirectly helps to clean up the environment. The Nitrogen Cycle The nitrogen cycle explains the how nitrogen flows between animals, bacteria, plants, the atmosphere, and the soil on earth. On the other hand, animals assimilate nitrogen by eating the plants. Tags: Question 9 . The nitrogen cycle refers to the cycle of nitrogen atoms through the living and non-living systems of Earth. Bacteria take nitrogen from air and convert it to nutrients in soil. Shares Share on Facebook. The majority (78%) of the Earth’s atmosphere is N2. Nitrites are formed by the oxidation of Ammonia with the help of Nitrosomonas bacterium species.

Still, this process is done by the nitrogen-fixing bacteria. Liberation Refuge (coming Feb 1st) presented by HumanMankind.com. Animals and humans eat nitrogen inside the plants. Biologically: Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. It occurs when the plant or animal dies then decomposers such as fungi and bacteria decompose the tissues and transforms the nitrogen back into ammonium. Nitrogen in the gaseous form cannot be absorbed and used as a nutrient by plants and animals; it must first be converted by nitrifying bacteria, so that it can enter food chains as a part of the nitrogen cycle. thanks for helping me understand this whole concept so well.
