The meeting of a predator and a prey often turns out to be fatal for the prey. However, there are many cases when the destruction of predator species ultimately leads to a sharp decrease in the number of prey species. why do you think?

The number of predators directly depends on the number of victims, and vice versa.

If the predators in the ecosystem are completely destroyed, then at first the number of prey will increase dramatically. This will happen due to the fact that there is no one to kill them, they will continue to reproduce, but due to the lack of a regulator, the population will not decrease. After a while, competition for food will intensify, diseases will spread in the population, and the number of victims will begin to decline, perhaps they will even completely disappear.
