The term "predator-prey" describes a biological relationship where one organism, the predator, hunts and consumes another organism, the prey. This interaction is essential for maintaining ecological balance, as it helps control population sizes and promotes biodiversity. Predators can include animals like lions and eagles, while prey can range from zebras to mice. In this relationship, both predators and prey have evolved various adaptations. Predators may develop sharper teeth or faster speeds to catch their food, while prey might evolve camouflage or heightened senses to evade capture. This ongoing struggle influences the evolution of species over time.
