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:Identify the macronutrients needed by prokaryotes, and explain their importanceDescribe the ways in which prokaryotes get energy and carbon for life processesDescribe the roles of prokaryotes in the carbon and nitrogen cycles
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 studying key processes in the carbon cycle, such as photosynthesis, composting and anaerobic digestion, students learn how nature and engineers "biorecycle" carbon. Students are exposed to examples of how microbes play many roles in various systems to recycle organic materials and also learn how the carbon cycle can be used to make or release energy.

The carbon cycle game is a short digital game that helps you teach how carbon atoms move through various forms including soils, the ocean, plant and animal life and fossil fuels. Actions such as photosynthesis, plant and animal death and forest fires all convert carbon from one form into another. This is a card style game. It allows for single or multi players. Runs on a browser.
Students will learn that there is a finite amount of carbon on earth, which moves around in the environment, from one place to another. Activity is scaleable from elementary to high school with options to introduce advanced content. Wrap up includes role playing the carbon cycle with the addition of human influences (e.g. burning of fossil fuels). Activity can be done in classroom or outside, includes working in a group and role playing. Grades 3-12. This resources is part of the Our Changing Ocean and Estuaries Series
Students are introduced to the concept of energy cycles by learning about the carbon cycle. They will learn how carbon atoms travel through the geological (ancient) carbon cycle and the biological/physical carbon cycle. Students will consider how human activities have disturbed the carbon cycle by emitting carbon dioxide into the atmosphere. They will discuss how engineers and scientists are working to reduce carbon dioxide emissions. Lastly, students will consider how they can help the world through simple energy conservation measures.
This series of 28 captioned images depict some the positive and some of the negative influences on the global carbon cycle, including industrial pollution, deforestation, waste disposal, transportation, and recycling. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change.
Students will construct a model of the carbon cycle to explore the cycling of matter in decomposition. Students will design a process to compost food waste and recycle products used during lunchtime to reduce the amount of garbage the school produces.
In this video, Jonathan examines the biology of coral reefs and their importance to the marine ecosystem. Please see the accompanying lesson plan that discusses pH and ocean acidification for educational objectives, discussion points and classroom activities.
Our planet is becoming hot. In fact, Earth may be warming faster than ever before. This warming will challenge society throughout the 21st century. How do we cope with rising seas? How will we prepare for more intense hurricanes? How will we adapt to debilitating droughts and heat waves? Scientists are striving to improve predictions of how the environment will change and how it will impact humans. Earth in the Future: Predicting Climate Change and Its Impacts Over the Next Century is designed to provide the state of the art of climate science, the impact of warming on humans, as well as ways we can adapt. Every student will understand the challenges and opportunities of living in the 21st century.
This is a unit plan where students will understand how Earth is systems of interacting components (spheres) and how changing one sphere will affect another. The carbon cycle is studied in quantity of carbon in each reservoir and how human and natural processes move carbon from one reservoir to another in two different time scales. The carbon cycle is studied qualitatively through demonstrations or labs with students developing models of the from of carbon in each reservoir.
" We will cover fundamentals of ecology, considering Earth as an integrated dynamic system. Topics include coevolution of the biosphere, geosphere, atmosphere and oceans; photosynthesis and respiration; the hydrologic, carbon and nitrogen cycles. We will examine the flow of energy and materials through ecosystems; regulation of the distribution and abundance of organisms; structure and function of ecosystems, including evolution and natural selection; metabolic diversity; productivity; trophic dynamics; models of population growth, competition, mutualism and predation. This course is designated as Communication-Intensive; instruction and practice in oral and written communication provided. Biology is a recommended prerequisite."
What is energy? It's the hot in heat, the glow in light, the push in wind, the pound in water, the sound of thunder and the crack of lightening. It is the pull that keeps us (and everything else!) from simply flying apart, and the promise of an oak deep in an acorn. It is all the same, and it is all different. Sunshine and waterfalls won't start your car, and wind won't run the dishwasher. But, if we match the form and timing of the energy with your needs, all of these things could be true. Energy in a Changing World is about the full arc of energy transformation, delivery, use, economics and environmental impact, especially climate change.
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.
