Decomposition is the process by which organic materials are broken down into molecules. Most organic matter in terrestrial ecosystems is broken down by decomposers found in soil and trash. Decomposers are organisms such as bacteria, worms, and fungi, which consume dead organic matter.
Abiotic factors are non-living physical or chemical factors, such as pH, soil, etc. Abiotic factors influence the decomposition rates. Abiotic factors may be grouped into the following categories: edaphic factors, climatic factors, and social factors.
The group of edaphic factors contains the type of soil or the geology of the land. The group of climatic factors contains temperature, sunlight, humidity, etc. Social factors include water resources, land use, etc.
The decomposition chamber is one of the three chambers in a self-sustaining ecosystem. The decomposition chamber represents the compost pile habitat.
