Straight from the bear’s mouth, the story of photosynthesis.

A heavily illustrated, 32-page book for young readers (grades 6-9) published in 1995 by Atheneum Press (Simon & Schuster). Two teenagers conduct experiments that prove that tiny aspen seedlings "eat" bear's breath in order to grow into large trees. Of course this is true, whenever they can get ahold of some. However, how do trees grow where there are no bears?
