Surplus killing can deplete the overall food supply, waste predator energy and risk their being injured.

Huffaker’s experimental universes showed that while under many circumstances predator–prey interactions will lead to extinction of both populations, interactions of spatial heterogeneity, dispersal ability of predator and prey species, and distribution of food sources can create an environment in which predator and prey species can coexist.
