Grizzly bears inhabit a variety of ecosystems, including forests, alpine meadows, tundra, and coastal areas. They are adaptable and can be found in a range of environments.Grizzly Bear Diet
Grizzlies are omnivores with a diverse diet. They feed on a variety of foods, including berries, roots, nuts, fish, insects, small mammals, and carrion. During certain times of the year, such as in the fall, they may consume large quantities of food to build up fat reserves for hibernation.Grizzly Bear Hibernation
