Abstract

The diversity of life on Earth raises the question of whether it is possible to have a single theoretical description for all organisms of the quantitative aspects of the organization of metabolism. However, similarities between organisms, like von Bertalanffy's growth curve and Kleiber's law on metabolic rate, suggest that mechanisms that control the uptake and use of metabolites are common to all organisms. These and other empirical patterns widespread in biology should be the ultimate test for any metabolic theory that hopes for generality. The present study (1) collects empirical evidence on growth, stoichiometry, feeding, respiration and energy dissipation and synthesizes it as stylized biological facts, (2) formalizes assumptions and propositions in a metabolic theory that is fully consistent with the Dynamic Energy Budget (DEB) Theory and (3) proves that these assumptions and propositions are consistent with the stylized facts.
