Saprophyte An organism that carries out external digestion of non-living organic matter and absorbs the products across the plasma membrane of its cells (e.g. fungi). Savannah The tropical grassland biome.
Oxidation of organic matter releases CO2 to the atmosphere, and regional and global impacts may result. dendrochronology The dating of past events and variations in the environment and the climate by studying the annual growth rings of trees.
It is a porous (allows water to move through it) mixture of decomposed organic matter (called humus) and some inorganic mineral particles (mostly rock fragments).
It can be formed from rotting organic matter (i.e., trash in a landfill), and seep up through soils or migrate through underground piping to the surface.
Chlorine gas is an extremely reactive and poisonous substance that rarely occurs in nature, but bonds quickly with organic matter to form a new class of chemicals called Organochlorines.
If organic matter decays when there is no oxygen present (anaerobic conditions or putrefaction), undesirable tastes and odors are produced.
The biological process that removes organic matter from wastewater using microscopic plants and animals (organisms). The activated sludge process imitates the natural process that a river, lake or stream uses to clean itself.

landfill: disposal of solid waste by burying it between layers of dirt in low-lying ground or excavated holes. Organic matter in landfill decomposes anaerobically (without air), gives off the greenhouse gas methane, ...
Biochemical oxygen demand (BOD) The amount of oxygen required to oxidize any organic matter present in a water during a specified period of time, usually 5 days. It is an indirect measure of the amount of organic matter present in a water.

Biomass energy is energy in the form of gaseous and liquid fuels, heat and electricity derived from organic matter of plant and animal origin.
Decomposition - The breaking down of organic matter to produce reduced or oxidized products such as NH3, NOx and CO2(g) and their subsequent release into the atmosphere. [Bioresource Technology, Vol. 98, 2526-2532, 2007] ...
Fouling: The deposition of organic matter on the membrane surface, which causes inefficiencies.
Fragmentation: The subdivision of a solid in fragments. The fragments will then adhere to the nearest surface.
The biochemical decomposition of organic matter, resulting in partial gasification, liquefaction, and mineralisation of pollutants.
Dike
A low wall that can act as a barrier to prevent a spill from spreading.
Biochemical Oxygen Demand (BOD): laboratory measurement of the amount of oxygen consumed by microorganisms while decomposing organic matter in a product.
Detritus: Nutritious mixture of digested and partly digested organic matter, bacteria, fungi, feces, etc.
Discharge: The amount of water flowing past a given point on a stream. Measured in cubic feet (or cubic meters) per second (cfs;cm/s).
Putrefaction: Biological decomposition of organic matter, with the production of ill smelling and tasting products, associated with anaerobic (no oxygen present) conditions.

methane: Methane is a flammable gas that is made when organic matter decomposes. It is a greenhouse gas.
mirage: A mirage looks like water in the distance but is actually shimmering light above a superheated desert plain.
Stabilization: Conversion of the active organic matter in sludge into inert, harmless material.
Stabilization Ponds: (See: lagoon.)
Stable Air: A motionless mass of air that holds, instead of dispersing, pollutants.
Mineralization: The release of inorganic chemicals from organic matter in the process of aerobic or anaerobic decay.
Mineralogy: The study of minerals; formation, composition, properties, classification and occurrence.
A colorless, odorless, flammable hydrocarbon (CH4) that is produced by the decomposition of organic matter, and other processes.
Bacteria- (Singular: bacterium) Microscopic living organisms that can aid in pollution control by metabolizing organic matter in sewage, oil spills or other pollutants.
A process of supplying or introducing air/oxygen into a medium which promotes biological degradation of organic matter in water.
Biomass - An energy resource derived from organic matter such as wood, agricultural waste and other living cell material.
A-Horizon - The uppermost zone in the Soil Profile, from which soluble Salts and Colloids are leached, and in which organic matter has accumulated. Generally this represents the most fertile soil layer and constitutes part of the Zone of Eluviation.

Compost is a mixture that consists largely of decayed organic matter and is used for fertilizing and conditioning land.
eutrophication
Adverse change in the chemical and biological status of a body of water following depletion of the oxygen content caused by decay of organic matter resulting from high primary production as a result of enhanced input of nutrients.
Turbidity: A cloudy condition in water due to suspended silt or organic matter.
