This chapter investigates the necessary conditions for the biomass in particular size ranges of a population to increase in response to an increase in mortality, and how the overcompensation comes about through a change in the population energetics. Ultimately, this overcompensation in stage-specific biomass solely results from the interplay between mortality and intraspecific, exploitative competition for resources among consumers. As a direct effect, mortality decreases overall density, but indirectly benefits survivors through the relaxation of competition for resources. This change in resource use by the consumer population may lead to biomass overcompensation, even in the absence of any increase in resource productivity.
