Explains the concept of a food chain and how plants, animals, and humans are ecologically linked. "What do you and tuna have in common? You and the tuna are part of a food chain. This food chain begins with green plants and ends with you at the top. Every link in a food chain is important, because each living thing depends on others for survival. Patricia Lauber and Holly Kelly will inspire you to draw your own food chains."--Dustjacket back.
