How many deer does one wolf eat in a year?

There's no simple answer to this question! Here's why:

* Wolf Diet: Wolves are opportunistic predators. They primarily eat large ungulates like deer, elk, and moose, but also smaller prey like rabbits, birds, and even berries.

* Availability: The number of deer a wolf eats depends heavily on how many deer are available in its territory. If deer are scarce, they might eat less. If deer are abundant, they might eat more.

* Pack Size: Wolves hunt in packs. The size of the pack affects how much food they need and how many deer they can kill. A larger pack can bring down bigger prey.

* Competition: Wolves also compete with other predators, like bears and coyotes, for prey.

Research Estimates:

Some studies suggest that a wolf pack of 5-7 members might kill 15-20 deer per year. However, this is just an estimate, and it varies widely depending on the factors mentioned above.

Instead of a specific number, it's more accurate to say that wolves eat as many deer as they need to survive and thrive, based on the conditions of their environment.
