a lot of sunlight to make a lot of food for the tree in warm weather
Small leaves reduce the effects of solar radiation and water loss.
For adaption when the weather gets cooler, the broad leaves cause too much water loss and can be weighed down by too much snow, so the tree drops its leaves.
Their primary prey is deer, but they also eat porcupines, raccoons, birds, small mammals, foxes, mice, and grass.
Animals in deciduous forests have to adapt to changing seasons. Some animals hibernate or migrate during the winter to escape the cold. Others grow thick fur and/or layers of fat to help make it through the winter months.
Tokyo, Osaka and Kyoto are within the temperate forest region. The temperate forest biome also covers Pyongyang in North Korea and Seoul and Busan in South Korea. In China, the major cities of Shanghai and Beijing fall in this zone.
