Deciduous trees are those that shed their leaves annually, usually in the fall. 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, which display vibrant colors before their leaves drop.
In contrast, evergreen trees retain their leaves throughout the year, providing a consistent green appearance. These trees, such as pine, spruce, and fir, have needle-like leaves that are adapted to withstand harsh weather conditions. Evergreens play a crucial role in maintaining ecosystems, providing shelter and food for various wildlife.
