ABSTRACT
In preceding chapters we described the goals of bioenergetics and the methods used in order to attain them. Due to the universal characteristic of the energetic unit, bioenergetics allows the interpretation of physiological or demographic phenomena to be simplified and the sensible comparison of species. Thus, bioenergetics brings new understanding of the metabolism of organisms and population dynamics. This is a fundamental role which justifies studies of energetics at cell, organism and population levels. Bioenergetics is also used in related applied or pure sciences.
