This book starts with this essential question and then goes on to examine the diets of sixteen different animals, from elephants and giraffes to sharks, woodpeckers, and even humans. The concepts of carnivore, herbivore, and omnivore are all introduced and then reinforced throughout with symbols for each animal. The book concludes with an explanation of food chains in three different environments. More challenging vocabulary is highlighted throughout, and the art and text work together seamlessly to help readers develop increased confidence in their reading skills.
