Abstract

Metabolisms are fundamental processes of organisms. These processes affect material recycling and energy transfer of the organisms in different environments. Metabolism determines the demands that organisms place on their environment for all resources, and sets powerful constraints on allocation of resources to all components of fitness. As the important index of life process, metabolic rate, setting the pace of life, was found to follow the allometric scaling relationship in many studies. For a heterotroph, the metabolic rate is equal to the rate of respiration because heterotrophs obtain energy by oxidizing carbon compounds. For an autotroph, the metabolic rate is equal to the rate of phot..
