Black bears,
polar bears, 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
brown bear eats berries, roots, fungi, grasses, fish, carrion, small mammals, and insects. Unlike the black bear, the brown 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 brown 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 also eats berries and other plants.
