What season is it when the leaves fall?

In general, every autumn, most deciduous plants and trees begin to shed their leaves, and the leaves are yellow and curly, falling from the trees and dancing with the wind, which also means that after late autumn, winter is coming. The north of China lies in the north temperate zone. In autumn, due to the low temperature, the rainfall decreases, the absorption of plant roots decreases, and the water and inorganic salts obtained by plants are greatly reduced, so that physiological activities such as photosynthesis, respiration and transpiration cannot be carried out normally. If leaves are left, a lot of water will transpiration, threatening the survival of plants. After cold and drought, new leaves will grow.

Therefore, when leaves fall, it is autumn.
