Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Discuss the biogeochemical cycles of water, carbon, nitrogen, phosphorus, and sulfurExplain how human activities have impacted these cycles and the potential consequences for Earth

By the end of this section, you will be able to:Describe the basic types of ecosystems on EarthExplain the methods that ecologists use to study ecosystem structure and dynamicsIdentify the different methods of ecosystem modelingDifferentiate between food chains and food webs and recognize the importance of each

By the end of this section, you will be able to:Describe how organisms acquire energy in a food web and in associated food chainsExplain how the efficiency of energy transfers between trophic levels affects ecosystem structure and dynamicsDiscuss trophic levels and how ecological pyramids are used to model them

This resource contains materials for chapters 11-15 and 19-21 from the Concepts of Biology OpenStax OER book by Rice University. It includes materials to be used for a General Biology II course (or Introduction to Biology II course) for non-science majors.

This open textbook covers the most salient environmental issues, from a biological perspective. The text is designed for an introductory-level college science course. Topics include the fundamentals of ecology, biodiversity, pollution, climate change, food production, and human population growth.

Lecture slides for each chapter are available from https://drive.google.com/drive/folders/119oj6XXHnQMpwu_rCgczDFrZPMbqGN8W

This is a survey course in which we will discuss the science behind historical and current environmental issues. We will discuss the major threats to biodiversity and ecosystem function. We will study how human activities have affected the limited resources of our planet. We will learn how air, water and soil degradation have affected human health. Lastly, we will explore the emerging field of sustainability, what it means, and how it is being applied in todayęs world.
