How do bears prepares for hibernation?
bears need to gather a lot of fat so they eat a lot before the winter then they make a den that might have some leaves and maybe a few berries
If some animals such as bears did not have hibernation as a control system what would happen to them?
'walking hibernation' means that the bears metabolism alters to a hibernation-like state which facilitates significant energy consercation. They remain active, but rely on stored fat for energy. This is a trait no other species of bear posesses. when the polar bear enters walking hibernation, their metabolism goes to a hibernation-like level. the polar bear remains active, but relys on stored body fat. the polar bear is the only bear that does this.
