What effect does the seasonal change have on the growth of animals and plants?

Abstract: For plants, seasonal changes are mainly the changes of temperature and sunshine. The specific factors affecting the growth of animals and plants are temperature and humidity, as well as light, moisture and food. The change of four seasons leads to the change of these factors. If the temperature, humidity and light in spring, summer, autumn and winter remain unchanged, the changes of the four seasons will not affect the growth of animals and plants. Therefore, the influence of four seasons on the growth of animals and plants is the change of temperature, humidity, light and other factors that affect the growth of animals and plants.

1. Seasonal variation covers many characteristics such as climate change and phenological change. The germination of spring, the prosperity of summer, the harvest of autumn and the storage of winter mark the development process of things.

(1) Spring: Due to the shortage of food supply throughout the cold winter, animals are generally thin and yellow. As the weather gets warmer, mammals begin to lose their thick fur. And gradually began to move to a safe area where food is gradually abundant. In spring, the qi of Yin and Yang begins to change, and everything germinates and grows because of Yang. Spring is the season when everything grows, cultivates and sows. The so-called "one year's plan lies in spring".

(2) Summer: animals have beautiful shapes and shiny fur. Animals will choose this time to form a family and reproduce. In summer, everything flourishes here, which is the season when crops enter the peak season. The temperature rises, the weather is hot, the storms are frequent, and everything is thriving. Summer is the most stormy season, often accompanied by strong winds and heavy rains.

(3) Autumn: Early autumn is affected by the climate, and the temperature difference between morning and evening is large, which is convenient for plant fruits to lock in more sugar. Therefore, the nutritional value of fruit in autumn is the highest. Animals will choose to store food or fat for the winter at this time. In late autumn, the climate turns from hot to cold, and everything grows, which gradually decreases with the cold. This is a season of alternating hot and cold. The most obvious change in autumn is that the leaves of plants and trees change from lush green to yellow, and they begin to shed leaves, while crops begin to mature.

(4) Winter: Animals are fatter. Affected by the climate, they began to become thick and warm fluff. The coat color of some animals even changes greatly, such as the mountain rabbit in the Arctic. The coat color is brownish gray (hay color) in summer and autumn, and white in winter, with large color difference. In winter, yin and yang change, everything is stored by the receiver, and plants are stored in a closed way. After entering beginning of winter, it means that the dry and rainy climate in autumn has gradually ended and turned into rainy, cold and frozen winter climate.

2. Animal food comes from plants. Plants are seasonal. Since spring, 10000 trees have been restored and plants have begun to grow rapidly. Therefore, since beginning of spring, animals will grow and reproduce quickly and get enough food. Animals and birds that migrate due to seasonal changes and lack of food will begin to return to their original habitats.

3. The specific factors affecting the growth of animals and plants are temperature, humidity, light, water and food. Seasonal changes lead to changes in these factors. If the temperature, humidity and light in spring, summer, autumn and winter remain unchanged, seasonal changes will not affect the growth of animals and plants. So the influence of four seasons on the growth of animals and plants, that is, the influence of temperature, humidity, light and other factors on the growth of animals and plants.
