Answer 3

Изменение окраски у деревьев и кустарников

а) Изменение окраски: The change in color of leaves in trees and shrubs, known as autumn foliage, is primarily triggered by the reduction of chlorophyll in the leaves as the days become shorter and the temperatures drop. This reduction in chlorophyll reveals other pigments, such as carotenoids and anthocyanins, which are responsible for the vibrant colors seen in the fall.

The process of changing leaf color is influenced by various factors, including temperature, sunlight, and soil moisture levels. Different species of trees and shrubs exhibit varying patterns and intensities of color change, leading to the diverse and beautiful autumn landscapes.

b) Листопад: Leaf fall, or "листопад" in Russian, refers to the natural process of leaves falling from trees and shrubs. This typically occurs in the autumn as part of the trees' preparation for the winter months. The shedding of leaves is an important adaptation that helps trees conserve water and energy during the colder and drier winter season.

The timing of leaf fall is influenced by environmental factors such as temperature, light, and moisture, as well as internal factors within the plants themselves. Different species of trees and shrubs may exhibit variations in the timing and duration of leaf fall, contributing to the seasonal changes in the natural landscape.
