Toward a Metabolic Theory of Ecology Toward a Metabolic Theory of Ecology


Ecology studies interactions between organisms and their biotic and abiotic environments. These interactions are fundamentally metabolic: metabolism is the exchange, transformation, and allocation of energy and materials by an organism. The metabolic rate of an organism varies with body size and temperature according to defined scaling relationships. Metabolic rates of organisms affect flows of energy and materials, rates of processes, and organization of systems at the levels of populations, societies, communities, ecosystems, and the biosphere. Metabolism holds out the promise providing the mechanistic basis for unified theory of ecology.
