Demands First Of All Knowledge On Animal Physiology

demands first of all knowledge on animal physiology which give us ekologo-physiological researches. For existence and normal functioning of a live organism energy is necessary. All energy necessary for it, the animal receives in the form of the chemical energy concluded in food. consumption of energy, or a power exchange, name intensity of a metabolism. Conveniently with sufficient accuracy to measure intensity of a power metabolism as speed of consumption of oxygen! The general consumption of oxygen - an integrated indicator of oxygen balance of the organism, reflecting specific to each kind of live beings intensity of a metabolism. Having revealed specific intensity of a metabolism it is possible to make a food allowance with sufficient accuracy and to spend calculation of efficiency of all trophic levels of separately taken food chain. The establishment of laws of change of a metabolism in the toxic environment promotes the decision of a problem of the forecast of efficiency of ecosystems in the conditions of anthropogenous pollution.
