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.

Constructing Sonoran Desert Food Chains and Food Webs
Read the Fine Print
Educational Use
Rating
0.0 stars

Is the food chain shown above accurate? Does the first link depict a producer, the second link a herbivore, and the third link an omnivore / carnivore? Students must correctly determine whether a species is a producer or consumer, and what type of consumer; herbivore, omnivore, or carnivore. Students are provided with a list of Sonoran Desert species and asked to construct, within their groups, several food chains. These food chains are then be used to construct a food web. In order to complete this activity, students must first research the individual species to understand their feeding habits.

Food Chains and Food Webs - Balance within Natural Systems
Read the Fine Print
Educational Use
Rating
0.0 stars

With a continued focus on the Sonoran Desert, students are introduced to the concepts of food chains and food webs through a PowerPoint® presentation. They learn the difference between producers and consumers and study how these organisms function within their communities as participants in various food chains. They further understand ecosystem differences by learning how multiple food chains link together to form intricate and balanced food webs. At lesson end, students construct food webs using endemic desert species.

Students will participate in a demonstration that will show the interconnectedness of a food web such that when one component is affected, the whole web is affected in some way. This is important for students to understand, as we are part of food webs and we need to be thoughtful about our decisions.

Got Energy? Spinning a Food Web
Read the Fine Print
Educational Use
Rating
0.0 stars

Students learn about energy flow in food webs, including the roles of the sun, producers, consumers and decomposers in the energy cycle. They model a food web and create diagrams of food webs using their own drawings and/or images from nature or wildlife magazines. Students investigate the links between the sun, plants and animals, building their understanding of the web of nutrient dependency and energy transfer.

Rating
0.0 stars

Students learn about energy and nutrient flow in various biosphere climates and environments. They learn about herbivores, carnivores, omnivores, food chains and food webs, seeing the interdependence between producers, consumers and decomposers. Students are introduced to the roles of the hydrologic (water), carbon, and nitrogen cycles in sustaining the worlds' ecosystems so living organisms survive. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

The Great Pacific Garbage Patch
Read the Fine Print
Educational Use
Rating
0.0 stars

The Great Pacific Garbage Patch (GPGP) is an intriguing and publicized environmental problem. This swirling soup of trash up to 10 meters deep and just below the water surface is composed mainly of non-degradable plastics. These plastic materials trap aquatic life and poison them by physical blockage or as carriers of toxic pollutants. The problem relates to materials science and the advent of plastics in modern life, an example of the unintended consequences of technology. Through exploring this complex issue, students gain insight into aspects of chemistry, oceanography, fluids, environmental science, life science and even international policy. As part of the GIS unit, the topic is a source of content for students to create interesting maps communicating something that they will likely begin to care about as they learn more.

Microeukaryotic gut parasites in wastewater treatment plants

Rating
0.0 stars

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Wastewater treatment plants are a critical piece of infrastructure that depend on microbes, both resident and incoming. Incoming microbes can be beneficial but may include parasites that need to be removed. Resident microbes, meanwhile, help break down organic waste. While much is known about bacteria in wastewater treatment plants, eukaryotes are frequently overlooked. Recently, researchers examined the whole microbiome of 10 wastewater treatment plants in Switzerland. They utilized metagenomics to measure which microbes were present and metatranscriptomics to analyze their activity. Bacteria were the most numerous— but eukaryotes, particularly protists, showed the most activity, and there was a surprising number and range of active parasites, which were particularly prevalent in the inflow. Network analysis suggested predation by resident microbes likely helped remove parasites..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Educational Use
Rating
0.0 stars

In this lesson, students will be amateur mycologists--collecting and analyzing various mushrooms. Through observation and discussion, students will gain knowledge of the basic anatomy of mushrooms, their life cycle, and their method of reproduction through spores. Students will learn to create spore prints of mushrooms and label and preserve their spore prints, just like a mycologist. Students also will learn that by comparing spore prints, they can identify different mushroom species.
