Predator-prey relationships are interactions between two species where one organism, the predator, hunts and consumes the other, the prey. This relationship is crucial for maintaining ecological balance, as it helps control prey populations and supports the survival of predators. Examples include lions hunting zebras or hawks catching mice. These relationships can influence the behavior and evolution of both species. Prey often develop adaptations, such as camouflage or speed, to evade predators. Conversely, predators may evolve better hunting techniques or physical traits, like sharper claws or improved eyesight, to increase their chances of capturing prey.
