Readers will climb through the pages of this vivid photographic book to explore the parts of a tree--and understand their functions. In summer, the tree sunbathes and seethes with animal life. With autumn comes the flowing sap that makes maple syrup for pancakes. As the tree's leaves begin to fall, winter is coming on and the tree is nearly dormant. Spectacular photographs and fun, informative text not only answer questions about how trees work and why seasons change but also make this book an invitation to observe and enjoy nature and its many wonders.
