All the biochemical processes in the biosphere may be reduced to synthesis and destruction of organic matter. During synthesis of organic substances from inorganic ones energy is absorbed from the environment. Conversely, energy is released in the process of destruction of organic matter. The energy content of organic substances (calorific coefficient), including hydrocarbons, fats, and proteins naturally differs from substance to substance. However, on average, the energy content per unit mass of organic carbon is approximately constant for most individuals in the biosphere and constitutes (Odum, 1983): $${K_{\rm{C}}} = 42{\rm{kJ/gC}}{\rm{.}}$$
