The Never-Ending Game: Predators and Prey
Imagine you're in the heart of a jungle, watching the never-ending game of hide and seek. This game is called the circle of life, and it involves predators and their prey. A predator is an animal that hunts and eats other animals, while the prey is the animal that gets eaten. For example, a lion is a predator, and a zebra is its prey. The predator-prey relationship is a key part of the food chain, where energy is transferred from plants to herbivores, and then to carnivores. For instance, grass, a zebra’s meal, gets its energy from the sun. When a lion, the predator, eats the zebra, that energy is passed on. This delicate balance is important for the health of our ecosystems. If any link in this chain is disrupted, it can cause a domino effect, impacting all animals and plants.
