Why do animals accumulate fat reserves before the onset of winter cold weather?

This is a way to protect the animal from hunger. In winter, there is practically no food for animals. For herbivores, food runs out and it is difficult for them to look for any food. Although predators do not feed on plants, they need prey, which are not so easy to meet in winter. Many of them are hiding. Therefore, stocking up on fat is a way to cope with a lack of food. Also, the fat layer helps not to freeze. Some animals store fat and continue to roam in winter, while others hibernate to survive the harsh conditions.
