Functions of living substance
Compared with other substances Biosphere (nutrient, rigid, radioactive substance, the scattered atoms and matter space origin) living substance plays greatest role and performs several functions. Between the rigid, lifeless, part of the biosphere, too rigid natural bodies and living organisms, its inhabitants, is a continuous flow of matter and energy. A steady stream of solar energy, green plants, absorbable is converted into chemical energy. Synthetic organic compounds (sugars, proteins, etc.), moving from one organism to another as a result of their food, are enclosed in them energy. Plants consumed by animals which, in turn, become victims of predators and t. d. this transition and there is a coherent and orderly flow of energy in the biosphere.
Energy is defined as the common quantitative measure of the movement and interaction of all types of matter. Its properties are described as the laws of thermodynamics. The first is the law of conservation of energy States that energy can change from one form to another, but it does not disappear and are not re-created. The second is the law of entropy – can be formulated as follows: the energy of any system is as thermodynamic equilibrium or maximum entropy. If the temperature of a body or surface of the Boulder or the site is valid, the land above air temperature, this system is to equilibrium. Boulder or land will give heat until its temperature is equal to the ambient air temperature. The energy of any living organism can be scattered in heat form. Finally comes the State of thermodynamic equilibrium and further energy processes become impossible. To the maximum entropy is not state of the organism or system must constantly draw energy from the outside and constantly strive to thermodynamic equilibrium. Otherwise, there comes the death of the organism and irreversible degradation of the system.
Some of this energy always dissipates as unusable heat energy. The efficiency of energy transformation of light into potential energy of chemical compounds in the green sheet is always less than 100 per cent .
