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 ]
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.

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.
Yahoo News: What does the decomposition process usually look like for a human corpse? Garvin: During decomposition, the body will undergo several phases. In early stages, you may get bloating or ...
Although the natural decomposition of human corpses into soil is a long-standing practice, a more rapid process that was developed in the early 21st century by Katrina Spade, entails encasing human corpses in wood chips, straw, and alfalfa until thermophile microbes decompose the body. [3]
Skeletonization refers to the final stage of decomposition, during which the last vestiges of the soft tissues of a corpse or carcass have decayed or dried to the point that the skeleton is exposed. By the end of the skeletonization process, all soft tissue will have been eliminated, leaving only disarticulated bones. [2]
In modern times, human cadavers are used for research, but other animal models can provide larger sample sizes and produce more controlled studies. [11] [12] Microbial colonization between humans and some non-human animals is so similar that those models can be used to understand the decomposition process for humans. [13]
Human remains that had been decomposing “for an extended period of time” have been discovered just off of a public hiking trail in Utah, police said. The Washington City Police Department ...
