Biology: Life on Earth, Books a la Carte Edition, 9th Edition

This edition features the exact same content as the traditional text in a convenient, three-hole- punched, loose-leaf version. Books à la Carte also offer a great value—this format costs 35% less than a new textbook.

Known for its thorough coverage of diversity, ecology, and environmental issues, this comprehensive book engages you with integrated, relevant case studies, and challenges you with thought-provoking questions throughout each chapter.   

The fully revised Biology: Life on Earth, Ninth Edition, has the same friendly writing style appreciated by thousands of students, but with greater emphasis on engaging, real-world applications. New to this edition are “Case Study Continued” sections, which connect a chapter’s case study to relevant biological topics covered in the chapter, and “Have you ever wondered?” features that respond to commonly asked questions from students. Thoroughly revised illustrations and expanded critical thinking questions have been added to each chapter.   

For coverage of plant and animal anatomy & physiology, an alternate edition—Biology: Life on Earth with Physiology, Ninth Edition—is also available.
