What would happen if bears were extinct in a food web?

Bears have very little predators besides humans and the occassional pack of wolves that stumble upon an ill or dying bear. This means that the only groups affected are their prey and other predators of their prey. This may cause a slight disturbance in the food web however, this difference will decrease as time goes by. The fact that there will be more of the bears' prey around and the fact that there will be more food for other predators of their prey will even things out over time.
