Bears: Facts (Science Trek)Learn about the eight different kinds of bears. Black bears live in the Americas, Europe, and Asia. Grizzly bears, native to North America, can weigh as much as six hundred pounds. Bears are big, but most are shy. Few are ferocious, but they aren't cuddly either. Newborn cubs weigh about half a pound. A one-year-old weighs about fifty pounds. Bears eat ants, plants, and baby animals. Berries are essential to gaining fat reserves to survive the winter. Weather doesn't impact hibernation, but food supplies determine when they go to their den.
