From The Hutchinson Unabridged Encyclopedia with Atlas and Weather Guide
Any animal that hunts, kills, and eats another animal (the prey). Predation is the method of feeding shown by a predator. Examples of predators include lions, which prey on antelope and zebra, owls, which prey on mice and rats, or sparrowhawks, which might prey on sparrows. Predators may affect the population size of their prey, and the population size of the prey may affect that of the predator. In a food chain predator and prey are placed next to each other to indicate the flow of energy from prey to predator. Predators may compete (see competition ) with each other for prey. If the prey is in short supply the numbers and biomass of predators will fall. Predators are usually bigger and more powerful than their prey (although a stoat preys on a rabbit, which may be four or five times its size), and their population is smaller – if the predator became more widespread than the prey, the population of the predator would inevitably fall. This is because there is not enough energy…
