What impacts did the wolf removal on the ecosystem ?

This would cause all the primary consumers to reproduce into an overgrown population.  

Explanation:

Secondary Consumers, like the wolf, help balance the population so that there is never too many of anything. So if wolfs disappeared, prey like deer, or some rodents, depending on habitat, would reproduce to fast to be slown down.

what's the question ?

nucleus

would be most reasonable answer tbh
