Predation - Wikipedia
Predation is a biological interaction where one organism, the predator, kills and eats another Sometimes predator and prey find themselves in an evolutionary arms race, a cycle of Ambush; Ballistic interception; Pursuit While examples of predators among mammals and birds are well known, predators. Over time, prey animals develop adaptations to help them avoid being eaten For example, when the prey becomes sparse, their density within a predator's. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words.
Though hypothetical, these scenarios cannot be ruled out. In fact, the relationship between predator and prey is more complex than what this example shows. What is a Predator-Prey Relationship?
Nearly all species in a given ecosystem are interdependent, to an extent that the loss of one species can have adverse effects on others. In a broad sense, the dependence can be classified into symbiotic relationships and predator-prey relationships. It shouldn't come as a surprise that the relationship between predator and prey has a crucial role to play when it comes to ecological balance.
A tilt on either side can trigger a domino effect on the environment as a whole. If, for instance, food supply is altered as a result of lack of prey, it will reflect on the population of predatory species, as they will find it difficult to reproduce in times of food scarcity. And like we said earlier, if the population of predators comes down, herbivores will run a riot in the ecosystem.
It's a classic example of the survival of the fittest.

In stark contrast to the cheetah-gazelle relationship is the relationship between African wild dogs and zebras. Wild dogs might be small, but they make up for it by resorting to pack behavior and their remarkable stamina.
The strategy is simple: As for zebras, they have the camouflage working in their favor, making it difficult for their predators to isolate and attack an individual. After analyzing the number of lynx and hare pelts brought in by hunters, Canadian biologist, Charles Gordon Hewitt came to a conclusion that the two species are highly dependent on each other, such that the population of the Canadian lynx rises and falls with a rise and fall in the snowshoe hare population.Predator prey cycle - Ecology - Khan Academy
Further research revealed that it was the food shortage resulting from the decline in hare population that affected the reproduction rate of this lynx species. While wildebeests and Cape buffaloes form a major chunk of their diet, African lions are also known to prey on warthogs, especially when they are easily available.
From the researchers' point of view, the relationship between wolves and moose on the Isle Royale gives the best picture of predator-prey relationships, as moose are almost the only prey for wolves on this isolated island.
After studying their relationship for decades, researchers have realized that the food shortage resulting from wolves eating too many moose, keeps a check on the wolf population as well. In the marine biome, the great white shark is the apex predator. It usually preys on elephant seals. For seals, the best line of defense is to stay on land. For the great white shark, its exceptional hearing skills help to locate the seal.
It is not always possible for the seal to stay out of water, lest it can die of hunger. The moment it gets into the water, it is on the great white's radar.
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf. Predator and prey evolve together. The prey is part of the predator's environment, and the predator dies if it does not get food, so it evolves whatever is necessary in order to eat the prey: Likewise, the predator is part of the prey's environment, and the prey dies if it is eaten by the predator, so it evolves whatever is necessary to avoid being eaten: This lizard abovecamoflauges by blending with the lichen on rocks, while the tortoise belowhas a hard shell to deter would-be predators.
In this snowy environment, the polar bear is white to avoid being noticed as it approaches the seal, and the seal pup is white to avoid being noticed by the bear. The fastest lions are able to catch food and eat, so they survive and reproduce, and gradually, faster lions make up more and more of the population. The fastest zebras are able to escape the lions, so they survive and reproduce, and gradually, faster zebras make up more and more of the population.
