Final answer:
If wolves were hunted to extinction in Yellowstone National Park, it would lead to the disappearance of many species, including the elk population.
Step-by-step explanation:
If wolves were hunted to extinction in Yellowstone National Park, it would lead to the disappearance of many species, including the elk population. Wolves are a keystone species in the Yellowstone National Park. They play a vital role in maintaining biodiversity in the ecosystem. If wolves were hunted to extinction, it would have a negative impact on the ecosystem. The loss of wolves would lead to an increase in the elk population, as there would be no predator to keep their numbers in check.
This would result in overgrazing of vegetation, leading to the disappearance of many plant species, which in turn would affect other species that depend on those plants. Therefore, the correct answer is option d: Many species, along with the elk population, would disappear.
The correct answer is option d.
