"This book explores the food chains and webs that exist in a grassland habitat. It equips readers with crucial vocabulary, using examples from that habitat to explain the roles of producers, consumers and decomposers, and illustrates how living things depend upon each other. Readers learn how fragile food chains can be, how they can be broken, and what we can do to prevent this."--
