'''Lindeman efficiency''' is the empirical regularity, first quantified by Raymond Lindeman in 1942, that only approximately 10% of the energy stored in biomass at one [[trophic level]] is converted into biomass at the next trophic level. The remaining 90% is lost to metabolic processes, heat dissipation, locomotion, and other life functions. This constraint, often called the '''ten-percent law''', is one of the most robust regularities in ecology and shapes the maximum length of [[food chain]]s, the biomass structure of ecosystems, and the vulnerability of apex predators to extinction.

The Lindeman efficiency is not a law in the strict physical sense but a statistical regularity arising from thermodynamic constraints on biological energy conversion. It connects ecology to [[thermodynamics]] through the second law: energy conversions are never perfectly efficient, and biological systems — operating far from equilibrium — must pay an entropic cost for every transfer. The efficiency varies across ecosystems and taxa, ranging from less than 1% in some aquatic systems to over 20% in highly efficient converters, but the 10% figure remains a useful rule of thumb.

The concept has been criticized for reinforcing the linear [[food chain]] model, since it is often taught as if energy flows through a single predetermined pathway. In reality, energy flows through [[food web|food webs]] along multiple edges simultaneously, and the Lindeman efficiency applies to each edge individually, not to the system as a whole. The network perspective reveals that Lindeman efficiency is a '''local''' constraint on individual predator-prey interactions, while the food chain model incorrectly treats it as a '''global''' property of the entire ecosystem.
