An unusual blend of narrative, poetry and science, this is an appealing introduction to the food web. Sayre’s lyrical prose describes leaves falling into a stream where, after their surfaces are softened by bacteria and algae, they are eaten by crane flies, shrimp and other “shredders.” These shredders are then eaten by unidentified predators, which are in turn eaten by trout. The text goes on to describe briefly the process of trout reproduction and then completes its journey through the food web with the final words: “Trout are made of trees. So are the bears and the people who catch the trout and eat them.” Endle’s illustrations feature, along with a vibrant natural setting in rich golden tones, two children actively engaged in observing and studying the stream. The illustrations, done in mixed-media collage, are a testament to the fact that wondrous new things can be created out of the pieces of other things, and thus, they reinforce the theme of interconnectedness that is the heart of this offering.
