Why did the population of deer decline drastically in 1925 even though their predators were eliminated?
When a predator species is eliminated from an ecosystem one of the natural consequences is an increase in the number of the target prey species. Over population results in over grazing/browsing (in the case of deer), stress and ultimately sickness and starvation.
Once the habitat has been over grazed, the number of animals it will support will generally be less than the number it could support before the initial damage caused by over grazing/browsing.
Without predation, the natural controls are starvation and disease caused by over population.
Population decreases could be further exacerbated by drought or other naturally occurring phenomena.

How does a change in the prey population effect the predator population?
A change in the prey population effects the predator population because if there are alot of preys, then the predators would eat the preys and the population of predators would increase. But on the other hand, if there are not enough preys, the predators would starve and die which would decrease the population of predators.

What happens to the predator population when the prey populations decreases?
The predator population may also decrease due to a decrease in available food source, leading to increased competition among predators. This could result in some predators migrating to find new prey or population decline due to lack of resources. Ultimately, the predator population may be negatively impacted by a decrease in the prey population.
