Metabolic scaling theory (MST) is an attempt to link physiological processes of individual organisms with macroecology. It predicts a power law relationship with an exponent of -4/3 between mean individual biomass and density during density-dependent mortality (self-thinning). Empirical tests have produced variable results. and the validity of MST is intensely debated. https://www.bekindtopets.com/mega-save-Harrows-Black-Knight-Soft-Tip-Darts-20gm-special-save/
