Signs of seasonal changes in trees.

Seasonal changes in trees are associated with a sharp change in weather conditions: air temperature, humidity, amount of solar radiation. Trees also change their biological rhythm due to changes in environmental conditions. The most striking example is a change in the color of leaves. Their color varies depending on the season and external conditions. Summer is considered the best time for photosynthesis, which is why the leaves are colored bright green. In autumn, the amount of sunlight is not so extensive, so the leaves lose their vitality.
