Predators and Prey E.g. In particular, predator-prey interactions have been examined from many angles to capture and explain various environmental phenomena meaningfully. Herbivory is a form of predation in which the prey organism is a plant. Some organisms, like armadillos, tortoises, porcupines and thorny plants, use armor, quills and thorns to defend themselves against predators.

When two unpalatable species resemble each other, they reinforce avoidance by predators by increasing the frequency of unfavorable encounters. Venomous snakes, spiders and wasps use poisons to either kill or immobilize their prey. You may remember that a predator is an animal that hunts and kills other animals for food.

A predator prey interaction occurs whenever a predator captures and eats an organism, which is known as the prey. Some defensive strategies are pretty obvious, and top among the list of obvious strategies is running away. Some organisms are themselves poisonous, like the poison dart frog. 2.

These tight evolutionary relationships can result in coevolution, when two species evolve in a coordinated fashion by adapting to changes in each other. However, for many of the earth's most biodiverse and abundant organisms, including terrestrial arthropods, these interactions are difficult or impossible to observe directly with traditional approaches.

The history of the study about the prey-predator interactions dates back long. Camouflage is a great defensive strategy, as evidenced by its widespread use in nature, but there is no rule that says it can only be used to hide from predators. Commensalism Overview, Examples & Types | What is Commensalism? Ecosystem-Consists of a given areas physical features and living organisms. A model of prey-predator interaction where the predator population is less strongly dependent on prey levels, prey density is held near its carrying capacity and predation is more likely to be influenced by risky behaviour on the part of the prey, is called predation- sensitive food hypothesis (Sih, 1982; Sih and More, 1990; Abrams, 1991).
