Question

what are the methods of by which decomposition occur

Answer 1

1 photochemical decomposition
2 electrical decomposition

Answer 2

Decomposition is the process by which organic substances are broken down into a more simple organic matter. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere. Bodies of living organisms begin to decompose shortly after death.Five general stages are used to describe the process of decomposition in vertebrate animals: Fresh, Bloat, Active and Advanced Decay, and Dry/Remains. The general stages of decomposition are coupled with two stages of chemical decomposition: autolysis and putrefaction.
