Predator-Prey Interactions Prey could obtain additional foraging opportunities by utilizing more of the landscape, while suffering compensatory costs from devoting additional time and energy to predator detection and defense. Humans are aware of such interactions, since we can observe them in the field; either orb-weaving spiders approaching their struggling prey caught in the web, or crickets ceasing singing when they detect vibrations created by our footsteps.

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. Predation is a biological interaction whereby one organism (predator) hunts and feeds on another organism (prey) Because the predator relies on the prey as a food source, their population levels are inextricably intertwined If the prey population drops (e.g. I can advise you this service - www.HelpWriting.net Bought essay here.

Predator-Prey Interactions Publisher: American Fisheries. Both predators and prey can use a variety of strategies in order to survive, including speed, flight, physical protection, camouflage, chemical compounds, mimicry and countless other strategies that we don't have time to talk about here. interaction, or prey{predator interaction. Use the graph to answer the questions. In particular, predator-prey interactions have been examined from many angles to capture and explain various environmental phenomena meaningfully. The interactions between a predator and its prey, as well as the interactions between an herbivore and the plants it eats, are some of the most powerful driving forces behind evolution.
