What happened to animals and plants in winter?

The changes of animals and plants in winter, when winter comes, deciduous trees lose their leaves and the growth of evergreen trees slows down or stops. Herbs are yellow, and the seeds go into dormancy, waiting for spring germination. Many things will change in winter. Let's share the changes of animals and vegetarians in winter.

Changes of Animals and Vegetarians in Winter 1 When severe winter comes, normal-temperature animals can use thick fur to resist the invasion of snow and ice, while warm-temperature animals hibernate to avoid the winter when food is scarce.

Annual plants often begin to bear fruit before winter comes, and with the help of fruits, they can continue their lives. Perennial herbs, some of which turn the aboveground parts yellow and die, live through the winter by buried stems or roots; Others shrink from the roots and hide the stems in the soil to resist the cold.

The more clothes people wear, the slower their metabolism will be to ensure that their bodies have enough calories.

Signs of life in winter:

Squirrels dig holes near winter to bury the food they find, and then sleep in tree holes in winter. When they are hungry, they get up and dig out the food buried in the ground to eat.

In addition, they can put eighteen pine nuts in their cheeks, fill them first, and then go to bed. But food is often dug up and buried by other peeping squirrels, and sometimes you forget what you buried.

Mantis can be made into large eggs, each with 300 to 400 eggs, which together with secretions form oocysts. Outside is a thick protective layer, attached to the trunk of the sun, not afraid of snow, ice and cold wind.

Negative worms lay eggs on their backs and then lurk in underwater soil for the winter.

Leaf-cutting bees transport piles of oval leaves into underground or hollow wood to build rows of beehives and form oval "houses". There is nectar or pollen in the house to lay eggs for winter. Each leaf-cutting bee can build 30 hives, and it needs at least 1000 oval leaves.

Larvae of scarab, obese and nutritious, hibernates in the deep soil.

With its naturally sharp mouth, the longhorn beetle digs a "tunnel" in the trunk, and its larvae spend the winter in this "tunnel".

There is a hard chitin shell outside the pupa of moth, which can bear the cold attack, and more fat is stored in the pupa, which can prevent frostbite.

From the larval stage, the debt-avoiding moth makes a "pocket" with bark and branches, carries it on her back or hangs it on the branches, and hides it in the "pocket" when she is at rest. In late autumn, I got into my pocket, turned into a pupa, and passed the winter safely.

In the deep winter festival, bees not only eat stored honey to get heat, but also "crowd together" around the queen bee to form a hive, so as to keep the temperature in the hive at about 35℃. If the bees in the outer layer are too cold to stand, they will "change their defenses" inside and outside. For those larvae, worker bees will feed 1300 times a day like competent nannies.

At the same time, worker bees also gather together to form an insulating layer to protect the larvae from the cold. If the larvae still feel cold, the worker bees will spread their wings and dance to raise the temperature of the hive.

The wasp has amazing cold tolerance and is still safe at -47℃.

Changes of animals and plants in winter 2 1, changes of plants in winter

Abnormal depression: After entering winter, the temperature began to drop, the growth of plants almost stopped, and most plants entered a dormant period. As people sum up from experience, winter is the season when everything sleeps. In winter, the temperature becomes very low, and with the cold wind blowing, the leaves of plants turn yellow and fall off, leaving only bare branches. Compared with other seasons, it will appear very lack of vitality and vitality, and it will appear extremely depressed. Because most plants have poor cold resistance, they will even freeze to death if they are outdoors, but this is a relatively normal phenomenon.

Improvement of cold resistance: after entering winter, plants enter deep sleep period, and their respiration is weakened, so the consumption of nutrients is reduced, and the metabolic intensity of the whole plant is also weakened a lot, which is conducive to the accumulation of nutrients such as sugar and can enhance stress resistance. In addition, the concentration of plant cell sap will also increase, which can lower the freezing point and play a role in self-protection. In the cold-resistant exercise year after year, the amino acid content of plants increases gradually, and the proline content also increases obviously, which can play an anti-freezing role and have a certain effect on plants adapting to adversity.

2. Changes of plants in autumn

Autumn is the season of falling leaves. After entering autumn, the leaves of some perennial plants will turn yellow, and then gradually wither and fall off, while annual plants may enter the end of their lives and slowly wither and die. In autumn, most plants will lose their leaves, because after entering autumn, the temperature will drop, the light will weaken and the rain will be less, so the water and nutrients absorbed by the roots of plants will be greatly reduced, which is not conducive to their normal photosynthesis and transpiration. In this case, if leaves are left, the water consumption of plants will be faster, which is not conducive to survival. Therefore, the most obvious change of plants in autumn is the withering and falling of leaves.

Changes of animals and vegetarians in winter 3 Which animals will change in winter?

1. In winter, the black bear lies in the cave. In order to reduce consumption and spend the winter safely, the central nervous system and metabolism enter a state of inhibition. Don't eat or drink, don't wake up, the body temperature drops to 2 or 2℃, and the heart rate is greatly reduced. I didn't wake up until the next spring and hibernated for five months.

2. Frogs and toads hibernate in the mud of the river bed in winter; Snakes also go underground to hibernate in winter, and some even go as deep as 1 or 5 meters. I didn't wake up until the next spring.

3. In winter, the brown feathers of Thunderbird will be replaced and turned white, which is beneficial to avoid natural enemies in the snow in winter.

In winter, the temperature drops, rivers freeze, snow falls, animals hibernate and so on.

1. Temperature drop: With the coming of winter, as the sun moves to the Tropic of Cancer on the other side of the earth, the temperature will drop below zero.

2. The river is frozen: the river will freeze because of low temperature, the liquid will become solid, and the fish in the river will hide in the deep water.

3. Snowing: The northern region is very cold from winter to spring, and the climate changes in several solar terms in winter are not obvious. Snow is the main feature of northern winter.

4. Animal Hibernation: When a cold current strikes, creatures will reduce their life activities, many plants will shed leaves, animals will choose to hibernate, and some are called hibernation. Migratory birds will fly to warmer places for the winter.

Winter:

Winter is one of the four seasons. Traditionally, beginning of winter is the beginning of mid-winter in 24 solar terms. In winter, life is closed and everything enters a state of recuperation. In winter, everything is collected. After beginning of winter, everything began to hide. The division of four seasons is usually based on the change of temperature, and the method of modern scholar Zhang Baokun is adopted. According to the method of four seasons, the average daily temperature is equal to or lower than 10 degrees Celsius for five consecutive days, which is regarded as entering winter.
