KEYSTONE SPECIES-WOLVES (CARNIVORY PREDATOR)

Wolves are an important keystone species, because they are one of the keystone species that maintains the balance of nature in an ecosystem. Wolves are the top of the food chain in Yellowstone Park, they eat the elks and other small animals that feed on plants, which provides oxygen to us. Wolves keep elk and deer populations in check. Too many deer will eat small trees, which leads to fewer trees. In turn, there would be fewer birds and beavers and the whole ecosystem would change. Too many elk would overgraze plants. As a result, they keep habitats healthy and going.
