Brown bears, also known as grizzly bears, are omnivores that eat a wide range of foods including meat, insects, fish, berries and plants. They live in forested and mountainous habitats across parts of Europe, Asia and North America. Adult grizzly bears typically grow to over 7 feet long and weigh between 500-800 pounds. Though once widespread, grizzly bears now only inhabit Alaska, Canada and remote areas of the western United States.

name is Ursus arctos horrbillis. Also you will
learn about their diet, habitat, average size
and body weight, range, map of range,
family life, life cycle, anatomy, and some
interesting facts.

3. Diet
Bears are omnivore which means they eat almost anything. A
grizzly bear has one of the most wide ranging diets of any living
animal. A healthy adult eats up to 35 Ib. (16 kg) of food each day.
