The ecosystem characterized by trees that shed leaves seasonally is known as a deciduous forest. These forests typically experience four distinct seasons, with trees losing their leaves in autumn to conserve water and energy during colder winter months. Common species found in deciduous forests include oak, maple, and beech. This ecosystem is prevalent in temperate regions, providing habitat for diverse wildlife, including mammals, birds, and insects. The seasonal changes also influence the ecosystem's dynamics, making it rich in biodiversity and fostering various plant and animal interactions.
