How do animals and plants survive winter?

We are about to enter a cold winter, if we do not pay attention to it in winter, animals and plants may freeze to death, so how do animals and plants survive the winter? Let's take a look at it.

How do animals spend the winter?

1. Hibernation: for example, snakes, frogs, turtles, etc., they sleep in their holes in winter. They didn't wake up until spring. For such a long time, they didn't eat, drink or move, and slowly consumed the fat in their bodies to get through the cold winter. Bears are also sleeping, but they will wake up at the slightest noise and come out to find something to eat when they are hungry. This is called false hibernation or semi-hibernation.

two。 Transfer place of residence: such as geese, swallows, etc. They fly to the warm south to spend the winter before winter comes. On the one hand, it is warm there, on the other hand, it can find food, which is conducive to their survival.

3. Thicken the fur or feathers on the body: such as rabbits, deer, foxes, sparrows, crows, etc., their fur or feathers are much thicker in winter than in summer, and they do not have to worry about what they eat, that is, they eat as much as possible in summer and autumn. Fat people eat when they can find food in winter, and they are not afraid to be hungry for a few days.

4. Store food: such as squirrels, bees, ants, etc. They store a lot of food in their homes in autumn, and they don't have to go out in winter.

5. Let the eggs through the winter: such as mantis, locusts, etc., they lay eggs in autumn and let the eggs spend the winter on the branches, in the grass and in the soil. The shape of these eggs is protected by special egg bags and is not afraid of the cold. When spring comes, their larvae will crawl out and play happily everywhere.

Second, how do plants survive the winter?

Plants will go into dormancy in winter, such as losing leaves, regulating water and so on.

1. The way the pines and cypresses spend the winter looks very advanced. Their leaf structure is relatively unique, in order to withstand the cold in winter, mainly by avoiding the emission of water to achieve the goal. The epidermis cell wall of the plant leaf is very thick, the epidermis cell closes when the weather is cold, at the same time, the root activity decreases, and the water content in the body is reduced.

two。 Some plants have their own tips for preserving heat. Most annual plants hide their energy in the seeds, which continue to thrive through transmission. For perennial plants, they store nutrients in their roots before winter to build up strength for growth in the coming year.

3. In addition, there are some plants that store large amounts of nutrients in their bodies, such as wheat and rape in winter, instead of hiding these necessary nutrients in seeds or roots, but reduce free water to withstand the severe cold.
