In a nutshell
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.
