This book explores the notion of various plants and animals that are linked together based on "who eats what." Children will learn about some simple food chains such as – leaf, caterpillar, wren and hawk. They also see how one plant or animal can belong to several food chains and that members or these related food chains (food webs) have a certain amount of dependence on each other. The text goes on to explain, through an example of a problem with over-hunted otters around the turn of the century, that when part of a food chain is disturbed, the other members will also be affected. There are some mild "environmental" messages in this text which our family used as an opportunity to discuss good stewardship of what God has given us.
