What Is the Origin of Decomposer Species

• Decomposition processes of the mammalian corpses follow a predicted sequence and represent normal physiology of mammalian death. Decomposition contributes to nutrient recycling, energy flow and limiting biomass accumulation. • Decomposer species are always present upon death and emerge in diverse environments i.e. soil, sterile soil ,water, concrete basements etc. • Decomposer species may result from the microevolution of gut bacteria consistent with the observation that they have greater functional capacity and cellular complexity than gut bacteria and can survive in ammonium rich environment. • Decomposer species may represent the first demonstration of microevolution of microorganisms.
