Black bears, polar bear and grizzly bears are members of the carnivora order, but they are omnivores.

Most of the black bear's diet consists of plants. In the summer months it eats grasses, herbs, sedges, fruits, berries and nuts. It also eats insects. Black bears don't hunt for meat, but if they happen to come across
carrion (a dead animal) they will eat it.

The
grizzly bear eats berries, roots, fungi, grasses, fish, carrion, small mammals and insects. Unlike the black bear, the grizzly bear is a hunter. It is very good at catching fish and it often uses its long claws to dig insects out of rotting logs and small mammals out of their burrows. Some grizzly bears in the Canadian Rockies hunt larger animals like moose, elk and goats.

The primary food source for the
polar bear is seals. It also eats fish, seabirds and sometimes, reindeer. In the summer it will also eat berries and other plants.
