In a Nutshell: A Life Cycle Nature Book for Kids About Change and Growth (Plants for Children, Gardening for Kids)

Here, in luminous illustrations, is the life cycle of an oak--and how it supports life even after it is gone. An acorn drops from a great oak and grows. Animals nibble at it, a fire threatens it, but overcoming many challenges it eventually towers high in the forest, observing the changing human scene below. Eventually its energy passes into many other life forms--even the cherry pie enjoyed by the boy in the house below.
