The human body is composed of approximately: 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. [1] The decomposition of soft tissue is characterized by the breakdown of these macromolecules, and thus a large proportion of the decomposition products should reflect the amount of protein and fat content initially present in the body.

Common wild pig (boar) corpse decomposition timelapse. Decomposition is the process in which the organs and complex molecules of animal and human bodies break down into simple organic matter over time. In vertebrates, five stages of decomposition are typically recognized: fresh, bloat, active decay, advanced decay, and dry/skeletonized. [1]
Generally, the term decomposition encompasses the biochemical processes that occur from the physical death of the person (or animal) until the skeletonization of the body. Putrefaction is one of seven stages of decomposition ; as such, the term putrescible identifies all organic matter (animal and human) that is biochemically subject to ...
The decomposition of food, either plant or animal, called spoilage in this context, is an important field of study within food science. Food decomposition can be slowed down by conservation. The spoilage of meat occurs, if the meat is untreated, in a matter of hours or days and results in the meat becoming unappetizing, poisonous or infectious.
An alkaline hydrolysis disposal system at the Biosecurity Research Institute inside of Pat Roberts Hall at Kansas State University. Alkaline hydrolysis (also called biocremation, resomation, [1] [2] flameless cremation, [3] aquamation [4] or water cremation [5]) is a process for the disposal of human and pet remains using lye and heat; it is alternative to burial, cremation, or sky burial.
Putrefying bacteria play a key role in decomposing and fermenting substances within the body as well as the body itself after death. Putrefaction is defined as the final step of decomposition after death. [3] Because these bacteria play a role in decomposition after death, putrefying bacteria also play a key role in the nitrogen cycle.
MacPlay re-launched as a publisher of Macintosh video games on the Mac App Store. The company in April 2015 released Pillars of Eternity on the Mac App Store. The company has published a number of other games such as Shelter 2 , Prison Architect , Human Fall Flat , and Cities in Motion .
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]
