Factors That Influence the Decomposition Rate of Organic - SFGATE A growing number of scientists view a corpse as the cornerstone of a vast and complex ecosystem, which emerges soon after death and flourishes and evolves as decomposition proceeds. The increasing oxygen consumed in the decomposition process robs other aquatic organisms of the oxygen they need to live. Adipocere starts to form within a month after death and has been recorded on bodies that have been exhumed after 100 years. A corpse generally progresses through five stages of decompositionfresh, bloat (autolysis), active decay (putrefaction), advanced decay and skeletonisation. Decomposition: fly life cycle and development times The presence of insects in a corpse is a critical clue towards estimating the time of death for bodies dead for longer periods of time. Increase in the dissolved oxygen concentration. The water flows out under the gill's cover and this process is repeated.
