G. BATESON has observed that energy expenditure of a living system can be an inverse function of its energy inputs.
He gives the following significant examples: “If you kick a stone, it moves with energy which it got from your kick. If you kick a dog, it moves with the energy it got from its metabolism. An amoeba will, for a considerable period of time, move more when it is hungry. Its energy expenditure is an inverse function of energy input”.
In P. VENDRYES terms, the system is able to counteract environmental perturbations if it possesses available and qualitatively adequate reserves (1942).
However, these reserves, when used, must be regenerated in due time by sufficient inputs.
