The type of tree that produces acorns is the oak tree. Oak trees belong to the genus Quercus and are known for their strength, longevity, and significant ecological roles. They provide habitats and food for various wildlife species, including birds, squirrels, and insects. Acorns, which are the seeds of oak trees, fall from the trees in autumn, and many animals rely on them as a food source. Oaks are prevalent in many regions globally and are often valued for their durable hardwood, making them popular for construction, furniture, and flooring.
