Its species occur in soils, oceans, lakes, rivers, and sewage disposal systems.Nitrous Oxide: Nitrogen oxide (N2O). A colorless, odorless gas that is used as an anesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream.Nitrification: A process facilitated by specialized bacteria involving the oxidation of ammonium to nitrite and nitrate.Nitrogen Cycle: The circulation of nitrogen in nature, consisting of a cycle of biochemical reactions in which atmospheric nitrogen is compounded, dissolved in rain, and deposited in the soil, where it is assimilated and metabolized by bacteria and plants, eventually returning to the atmosphere by bacterial decomposition of organic matter.Aquatic Organisms: Organisms that live in water.Seawater: The salinated water of OCEANS AND SEAS that provides habitat for marine organisms.Mitosporic Fungi: A large and heterogenous group of fungi whose common characteristic is the absence of a sexual state.
