Every living thing needs food to survive. Food gives living things the energy they need to live, grow, and move. In the study of life science, food webs and food chains exist to display the order of who eats who. As readers discover in this volume, carnivores, omnivores, herbivores, and scavengers have unique diets and eating habits. With full-color photographs, diagrams, and accessible text, this volume will engage readers from start to finish and further their knowledge of essential life science topics.
