Predator-Prey Interactions Predation is a density
... Predation is a density-dependent limiting factor; it is affected by the number of individuals in a given area. For example, the population of a predator can be limited by the amount of prey available. The opposite is true as well. The population of a prey species can be affected by changes in its pr ...
