Children's LiteratureWhat do a fern, beaver, eagle and mushroom have in common? Each is a part of a forest food chain. With photos and beautifully drawn graphics, this title connects each of these seemingly unrelated animals and plants and succinctly defines a food chain. Explanations on photosynthesis, population control, predators and prey, and detritus food chains are deftly laid out so that younger readers can understand how natural cycles work in our world. Kalman places this knowledge in context by closing the book with a discussion of how forests are currently in danger and what we can do to help. Understanding how food chains provide the energy we need to live and work and play gives the proper background for children to grasp environmental issues that adults continue to grapple with. 2005, Crabtree Publishing, and Ages 8 to 12.
