When one species called predator, preys on other species, this interaction is called predation. and prey. /Filter /FlateDecode She is modeling the impact of predator hunting strategy and fluctuating resource conditions on the strength of prey avoidance behaviors in response to predictable levels of predation risk. Both the predator and prey are influenced by other ecological interactions. While some animals rely on camouflage, others, especially those with chemical deterrents, have bright or distinctive markings that serve as a warning to would-be predators called warning coloration.
