Universal Life Energy–Growth Framework and Equation (Applicable to Humans, Animals, Plants, Fish, Birds, Insects, and Other Living Systems)

All living organisms function as open, nonequilibrium thermodynamic systems that maintain biologicalorder by continuously absorbing matter and energy from the environment and converting these inputsinto chemically usable forms. Despite major advances in physiology, ecology, and bioenergetics, aunified interpretive framework linking resource uptake, metabolic efficiency, and growth dynamicsacross diverse taxa remains limited. This paper introduces a systems-level Universal Life Energy–GrowthFramework applicable to humans, animals, plants, fish, insects, and other living systems. The modelintegrates three fundamental biological dimensions: (i) resource absorption mediated throughphysiological interfaces, (ii) metabolic conversion efficiency governing chemical energy transformation,and (iii) temporal dynamics of mass change reflecting developmental or environmental constraints.From these principles, a generalized uptake–energy–growth relationship—referred to as the UniversalLife Energy–Growth Expression—is formulated. The framework does not claim to establish a universalphysical energy law, nor does it quantify energy in mechanical units. Instead, it provides a biologicallygrounded, cross-species interpretive structure consistent with metabolic scaling theory, ecologicalenergetics, and life-history concepts. Its primary value lies in supporting comparative analysis,identifying limiting factors, and generating hypotheses regarding biological productivity, growth, andreproductive performance across environmental and physiological contexts.
