What is the relationship between a predator and a prey?

A predator is an organism that kills and feeds on other organisms.

The organism that is eaten is called the prey.




Their relationship

As the predator feeds on the prey, the number of predators depends on the number of prey.

For example, zebra (prey) and lion ( predator),

When there is an increase in the number of zebras, the lions will have a lot of prey to prey upon, and thus the lions will also reproduce faster.

Subsequently, due to the increasing amount of lions, there will be lesser zebras.

Thus, with the decreasing number of zebras, some of the lions will starve and the lion population will decrease.

After that, with lesser predators, the zebra population will increase again.

The cycle continues.
