Broadleaf trees are a type of tree characterized by their wide, flat leaves. These trees are typically found in temperate and tropical regions and can be deciduous, shedding their leaves in the fall, or evergreen, retaining their leaves year-round. Common examples of broadleaf trees include oak, maple, and birch. Broadleaf trees play a vital role in ecosystems by providing habitat and food for various wildlife. They also contribute to air quality by absorbing carbon dioxide and releasing oxygen. Additionally, their leaves help to regulate temperature and moisture in their surroundings, making them essential for maintaining healthy environments.
