Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Describe the effects of abiotic factors on the composition of plant and animal communities in aquatic biomes
Compare and contrast the characteristics of the ocean zones
Summarize the characteristics of standing water and flowing water freshwater biomes

Discover the hidden treasures in the different habitats on the earth! The earth is filled with many biomes. Examples of different biomes are listed and include hyperlinks to additional information such as the animals found there.
