The black bear’s primary diet is fruit, nuts, honey, and berries. However, they also like to eat fish and small mammals. Their long, sharp claws make it possible to climb trees in order to reach some of their food sources. Black bears also have an extremely good sense of smell. Their long nose allows them to smell up to 20 miles away. This is 100 times better than humans can smell. The black bear’s tongue is sticky allowing them to easily eat ants, berries, and nuts. Black bears also have extremely strong legs, allowing them to move rocks and other obstacles out of their way to get to their food. SELECT ONE EXAMPLE OF THE PHYSICAL ADAPTATIONS LISTED ABOVE.
