Deciduous refers to trees and shrubs that shed their leaves annually, typically in the autumn. This process helps them conserve water and energy during the colder months when sunlight is limited. Common examples of deciduous trees include oak, maple, and birch. These plants usually have broad leaves that change color before falling off, creating beautiful autumn landscapes. Deciduous forests, found in temperate regions, support diverse ecosystems and provide habitats for various wildlife, including birds and mammals. The cycle of leaf loss and regrowth is essential for the health of these ecosystems.
