Answer:
The predators would consume the prey population faster than it could be replaced.
Explanation:
According to Oxford dictionary; an ecosystem is "a biological community of interacting organisms and their physical environment."
An ecosystem is a self supporting unit that is composed of living and non living parts. The ecosystem should be self sustaining.
In the particular case mentioned in this question, when the predator population becomes so large, they will steadily diminish the prey population faster it can be replaced thereby distorting the balance of the ecosystem.
