How has the brown bear adapted to its environment?
Let’s back up. One of the brown bear’s adaptations is that it hibernates, or remains inactive and essentially sleeps, during the winter. This is a strategy for surviving the cold season. Before hibernation, the brown bear has to build up a thick layer of fat by eating up to 90 pounds of food every day.
How do grizzly bears adapt to their environment?
Grizzly bears are specially adapted to survive the changing seasons. During warmer months, they eat a massive amount of food so they can live off body fat during the winter, when food is scarce. In the fall, as temperatures cool and food becomes scarcer, grizzlies dig dens in the sides of hills.
What adaptations help bears survive?
Those huge, strong legs allow the bear to move or bend large objects like rocks, tree trunks or limbs that get in the way of him and the food.
