Changes occurring in plants and animals in the autumn period in nature.

In the fall, animals and plants begin to actively prepare for the onset of cold weather. Plants and animals are actively stocking up on organic matter. Plants store glucose, and most animals store fat. Most trees and shrubs shed their leaves as they cannot survive the cold. In addition, they remove all unnecessary and toxic substances into the leaves. Animals can hibernate or simply prepare a supply of nuts, bark and other things (for rodents that do not hibernate).
