What would happen if an animal suddenly disappeared from an ecosystem?

If one animal disappears, that’s a loss of food for another animal. For example, if rabbits disappeared off of a food web, the predator, lets say it’s a fox, would have a loss of food. So rabbits disappear, foxes lose food, if the foxes don’t have food, they could die out, causing the foxes predator to die, etc.
