Hibernation is the animal's way of adaptation in order to be
able conserve energy by staying inactive and lowering its physical activity in
preparation for future purposes say for example a bad weather. Other animals also hibernate in preparation
for a long drought or scarcity of food. They tend to consume a lot of food
before the scarce and will use the accumulated energy during the drought when
there will be no more food to eat. It is a way of recharging themselves.
