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]
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 .
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 law of biogenesis, attributed to Louis Pasteur, is the observation that living things come only from other living things, by reproduction (e.g. a spider lays eggs, which develop into spiders). Fertilisation (Conception) – the beginning of an organism's life, initiated by the fusion of gametes resulting in the development of a new ...
The expression first appeared in print via the title of a 1920 book, Die Freigabe der Vernichtung Lebensunwerten Lebens (Allowing the Destruction of Life Unworthy of Life) by two professors, the jurist Karl Binding (retired from the University of Leipzig) and psychiatrist Alfred Hoche from the University of Freiburg.

Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
Death is the end of life; the irreversible cessation of all biological functions that sustain a living organism. [2] The remains of a former organism normally begin to decompose shortly after death. [ 3 ]
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 ...
