Exponential growth and allometric equations

Abstract

Earlier the simple exponential growth law has been used when attempts have been made to explain theoretically the existence of allometric equations in biology (Bertalanffy, 1968; Giinther, 1975). We show here that the exponential growth law in which the proportion coefficient also depends on time is a better approximation. We consider especially the metabolic rate and the body mass of man during the growth process.
