Final answer:
When hunters excessively kill deer, wolves, as a keystone species, will likely move to other areas to find food, which may then lead to ecosystem imbalance.
Step-by-step explanation:
In a forest ecosystem, if hunters kill too many deer, affecting the deer population negatively, wolves that rely on deer for food may experience a scarcity of prey. As a result, wolves would most likely move to other areas to find food. If they cannot find an alternative food source or migrate, the wolf population may decrease due to starvation. This scenario demonstrates the importance of predator-prey dynamics in ecosystem balance. Wolves are known as keystone species because they have a disproportionately large effect on their environment relative to their abundance. The absence or decline of a keystone species can lead to significant changes in ecosystem structure and dynamics, such as increased populations of other species, changes in vegetation, and effects on other predator and prey species.
