how do you know the answer is wolves
In this ecosystem, wolves play a crucial role as they are at the top of the food chain, preying on both deer and foxes. If wolves were to be absent from the ecosystem, there would likely be an overpopulation of both deer and foxes. The absence of wolves could result in an increase in deer population, causing overgrazing and ultimately leading to a decline in vegetation and other species that rely on the ecosystem for food and habitat. Additionally, if foxes were to overpopulate without a predator like wolves to keep their numbers in check, it could potentially lead to a decrease in rabbit population, disrupting the balance of the ecosystem. Therefore, the absence of wolves would likely have the greatest negative effect on the ecosystem.
