Predator-prey is an ecological relationship between organisms in which one organism kills or hunts the other organism and eats it for nutrition.
The organism which kills the other organism is termed as predator and the organism which gets killed is termed as prey.
For example, tiger and deer follow the predator-prey relationship in which the tiger is the predator and deer is the prey.
Similarly, polar bears are the predators of the seal as they hunt and eat the seals.
