The very nature of living tissues is to maintain physiological stability. This is essential in varying and often hostile environments. There are numerous physiological and biochemical systems involved in maintaining cell wall/membrane integrity. In organisms t-cells and other antibodies are part of the immune system which protects cell tissue. Dead organisms no longer function as a system and are no longer be able to maintain or provide the required defence against bacterial or fungal attack. Decomposition is the break down of these tissues/cells into their chemical components which are either digested by de-composers or released directly into the environment.
