How do geese, ants and rabbits adapt to the cold winter respectively?

There are three kinds of animals that are very hardy:

These geese migrate south. Goose originally lived in the northern part of the northern hemisphere (or the southern part of the southern hemisphere). Because of the arrival of the ice age, the whole world became cold. In winter, cold air pushes from north to south (from south to north in the southern hemisphere), driving birds in the northern hemisphere to flee south (from north in the southern hemisphere), and then returning to their original habitat in summer, forming the instinct of migration. In winter in the north, the temperature drops below freezing point, and the lake and sea surface freeze, making it impossible for waterfowl to prey; Even more deadly, the drop in temperature caused almost all insects to freeze to death or hibernate, and birds that feed on insects also lost their food sources. Such food shortage is the main reason for forcing birds in the northern hemisphere to move south (birds in the southern hemisphere move north).

Ants hibernate. Ants are temperature-changing insects and are extremely sensitive to low temperature. Ants spend the winter in the underground part of their nests. When winter comes, when the temperature is below 10℃, they nest underground and hibernate. During hibernation, ants don't eat, drink or move, and their metabolism drops, so they can survive the cold winter safely. Compared with the active state, the metabolism of dormant ants is not only slow, but also significantly different in quality. Ants basically consume fat during dormancy. Ants in the natural environment have to resist the harsh environment and consume a lot of nutrients in the body. Not only not long, but also thin.

Rabbits hibernate. Rabbits will have their own caves in winter, and there will be a lot of firewood in the caves. Bunny will use these firewood to keep warm. At the same time, the rabbit will eat a lot of plants, hoard body fat and grow a lot of hair before winter, which is equivalent to wearing a thick cashmere coat for himself, and the warmth retention effect will be further improved. Rabbits don't come out in winter Only when they are short of food will they come out for food, otherwise they will all be near the cave. Rabbits like to live in the sandy desert areas of mixed forests and grasslands in Shui Mu, especially in the spiny young forests in Yanghuai. Where there are the following three conditions, there will be more rabbits, otherwise there will be fewer rabbits.
