Key difference: Predator hunts Prey. The Lotka–Volterra predator–prey model was initially proposed by Alfred J. Lotka in the theory of autocatalytic chemical reactions in 1910. They have great environmental adaptations to win the battles against predators by their hiding, escaping, and fighting skills; sometimes even with the chemical weapons.

So, both these animals are necessary in order to maintain the ecological balance. Prey that is too small may not be worth the trouble for the amount of energy it provides. Predators are the ones who hunt other animals; while preys are the ones who are hunted or attacked by other animals. Both, of these animals are necessary for maintaining the ecological balance of the Earth. They can also adopt behaviour that avoids predators by, for example, avoiding the times and places where predators forage.Prey animals make use of a variety of mechanisms including Animals avoid predators with behavioural mechanisms such as changing their habitats (particularly when raising young), reducing their activity, foraging less and forgoing reproduction when they sense that predators are about.Eggs and nestlings are particularly vulnerable to predation, so birds take measures to protect their nests.By forming groups, prey can often reduce the frequency of encounters with predators because the visibility of a group does not rise in proportion to its size. the prey is part of the predator's environment, and the predator dies if it does not get its prey; as the predator is fully dependent on prey for its basic living.Both evolve together, i.e. There are several mechanisms that produce this effect.

The capturing of prey for food.


An alternative explanation is A more symmetric arms race may occur when the prey are dangerous, having spines, quills, toxins or venom that can harm the predator. Like that of predator, even the preys are a part of predator’s environment; i.e. Predators may actively search for or pursue prey or wait for it, often concealed.

An ecosystem is a community of animals, plants, micro-organisms, non-living things and their shared environment.
n. 1. Predator and prey are inter-related to each other; i.e. This may involve Predators are adapted and often highly specialized for hunting, with acute senses such as At the most basic level, predators kill and eat other organisms. One is Chemical defences include toxins, such as bitter compounds in leaves absorbed by leaf-eating insects, are used to dissuade potential predators.When a predator is approaching an individual and attack seems imminent, the prey still has several options. a predator evolves whatever is necessary it can do in order to get the prey.

The prey-predator relationship maintains the ecological balance of the earth, as if predators won’t be there then the prey population would increase in earth, which would give rise to over grazing and hence this would directly affect the natural plant life circle. However, when the prey is capable of killing the predator (as can a In the absence of predators, the population of a species can grow exponentially until it approaches the Cyclical fluctuations have been seen in populations of predator and prey, often with offsets between the predator and prey cycles. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). Alien vs.

This differs from ambush predation in that the predator adjusts its attack according to how the prey is moving.In pursuit predation, predators chase fleeing prey. is a term used to describe organisms that predators kill for food.Predator/prey relationships can be illustrated in a diagram called a A food chain shows the linear flow of energy between organismsA food web shows the energy flow through interconnected food chains in an ecosystem make their own food using energy from an abiotic source. Avoidance is not necessarily an evolutionary response as it is generally learned from bad experiences with prey. Divided between predator and prey, the animal citizens of Zootropolis enjoy an uneasy truce. Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey.

Prey is a necessary part of the ecosystem, especially to facilitate the flow of energy to predators; as if there were no preys then there wont had been predators also on earth.The prey-predator relationship maintains the ecological balance of the earth, as if predators won’t be there then the prey population would increase in earth, which would give rise to over grazing and hence this would directly affect the natural plant life circle. A bird foraging for insects spends a lot of time searching but capturing and eating them is quick and easy, so the efficient strategy for the bird is to eat every palatable insect it finds. In the ecology, these are co-related to each-other. If detected, they can try to avoid being the target of an attack, for example, by signalling that a chase would be unprofitable or by forming groups.
