Decomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere .
Whether the decomposition of an organic compound will result in mineralization or immobilization is dependent on its concentration proportionate to that of the carbon in the organic matter. [ citation needed ] As a rule of thumb, if the concentration of a specific element exceeds the needs of the decomposer for biosynthesis or storage, then it ...
In the breakdown of a compound into its constituent parts, the generalized reaction for chemical decomposition is: AB → A + B (AB represents the reactant that begins the reaction, and A and B represent the products of the reaction) An example is the electrolysis of water to the gases hydrogen and oxygen: 2 H 2 O(l) → 2 H 2 (g) + O 2 (g)
Decomposition is often erroneously conflated with this process of external digestion, probably because of the strong association between fungi, which are external digesters, and decomposition. The term "decomposer" refers to a role in an ecosystem, not to a particular class or type of organism, or even to a specific capacity of those organisms. [5]
Permutation decomposition, decomposition of a permutation into disjoint cycles; Primary decomposition, decomposition of ideals into primary ideals; Vector decomposition, decomposition of vectors into components or coordinates of basis vectors; Wavelet decomposition, re-expressing a given function as the sum of a series of wavelet functions
For example, at 2,200 °C (2,470 K; 3,990 °F) about three percent of all H 2 O are dissociated into various combinations of hydrogen and oxygen atoms, mostly H, H 2, O, O 2, and OH. Other reaction products like H 2 O 2 or HO 2 remain minor. At the very high temperature of 3,000 °C (3,270 K; 5,430 °F) more than half of the water molecules are ...
Decomposition in animals is a process that begins immediately after death and involves the destruction of soft tissue, leaving behind skeletonized remains. The chemical process of decomposition is complex and involves the breakdown of soft tissue, as the body passes through the sequential stages of decomposition . [ 2 ]
This is an important technique for all types of time series analysis, especially for seasonal adjustment. [2] It seeks to construct, from an observed time series, a number of component series (that could be used to reconstruct the original by additions or multiplications) where each of these has a certain characteristic or type of behavior.
