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:

Explain the significance of photosynthesis to other living organisms
Describe the main structures involved in photosynthesis
Identify the substrates and products of photosynthesis

What do you know about animal nutrition? Animal nutrition encompasses the dietary needs of animals, primarily those in agriculture and food production, but also in zoos, aquariums, and wildlife management. Learning objectives: Describe the seven major classes of nutrients. Describe the various digestive systems of animals. Identify careers that are involved in animal nutrition. Explain how soy is important to animal nutrition.

In this threaded PBL*, (an effort to integrate agricultural understandings into the normal sequence of an Environmental Science classroom) students will conduct several “close reads” (reading for understanding, analysis and application) which expose students to the science and engineering that is required to understand what farmers have to consider as they produce crops. These close reads take complex content and make it readable for students who are in middle school or high school and allow the teacher to incorporate literacy skills within their classroom. In the last section, students will conduct a real life simulation that illustrates a decision-making process to determine the application of chemicals to a fictional farm while addressing the needs of controlling specific nuisance weeds. Students will take a position on the application of chemicals to a field and defend their statement. This unit features 7 lessons and 12 files. Lessons are aligned to NGSS.

How have we developed the crops we eat today? What did these plants look like in the wild? Students will learn about the various techniques and technologies that plant breeders have used to create the plants we harvest to feed people and livestock. By the end of this course, you will: describe selective breeding and some of the food crops that have resulted from its use, describe mutagenesis and how it has impacted food production, understand the mechanism of genome editing and CRISPR technology, discover the current applications of CRISPR in agriculture.

Understand and appreciate food producers through this case study and determine what decisions must be made on a yearly, monthly, or daily basis to maintain an environmental system that will continue to produce food and products to meet consumer demands while maintaining soil and water quality. This unit features 3 lessons and 7 files. Lessons are aligned to NGSS.

As concerns grow about the sustainability of meat production, some startup companies say they may have a solution: growing meat from animal cells in laboratories. NewsHour Weekend's Megan Thompson visited two startups in California producing "cell-based meat." This story is part of our "Future of Food" series, hosted by Mark Bittman and supported by the Pulitzer Center. [11:35]

Explains what aquaculture is, the different types, the benefits it offers, and its impact on the environment.
