The introduction of a predator breaks the equilibrium

Let's see how the introduction of a new predator (at TIME = 50) affects our system in equilibrium.

Example's trophic chain

As you can see, the introduction of a new predator causes a decrease on the population of the herbivore. Because of this decrease, an increase on the population of the plants takes place.
