A deciduous tree is a type of tree that sheds its leaves annually, usually in the fall. This process helps the tree conserve water and energy during the colder months when sunlight is limited. Common examples of deciduous trees include oak, maple, and birch. Deciduous trees are found in various climates around the world, particularly in temperate regions. They play a vital role in their ecosystems by providing habitat and food for wildlife. Additionally, their seasonal leaf changes contribute to the beauty of landscapes, especially during autumn when leaves turn vibrant colors.
