Universal Life Energy–Growth Framework and Equation

All living organisms function as open, nonequilibrium thermodynamic systems that maintain biological order by continuously absorbing matter and energy from the environment and converting these inputs into chemically usable forms. Despite major advances in physiology, ecology, and bioenergetics, a unified interpretive framework linking resource uptake, metabolic efficiency, and growth dynamics across diverse taxa remains limited. This paper introduces a systems-level Universal Life Energy–Growth Framework applicable to humans, animals, plants, fish, insects, and other living systems. The model integrates three fundamental biological dimensions: (i) resource absorption mediated through physiological interfaces,…
