Students are introduced to the classification of animals and animal interactions. Students also learn why engineers need to know about animals and how they use that knowledge to design technologies that help other animals and/or humans. 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.

Cocos Island, a remote volcanic summit in the middle of the Pacific Ocean, serves as a beacon for hungry predators, including thousands of hammerhead sharks that travel here each year in search of prey. This video segment from NOVA: "Island of Sharks" depicts some of the common predator-prey interactions that take place in the nutrient-rich waters surrounding the island.

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:Describe the effects of abiotic factors on the composition of plant and animal communities in aquatic biomesCompare and contrast the characteristics of the ocean zonesSummarize the characteristics of standing water and flowing water freshwater biomes

After making observations and inferences about predator-prey relationships in their schoolyard, students work together to build food chains of the organisms they observe.

After learning about food chains, students practice building food chains and design their own backyard food chains.

Students create a kelp forest or coral reef food web, then research related shark species to learn about species interactions. Posters illustrate the shark̢ĺŰĺŞs role as key predator in the ecosystem.

Students will be introduceed to the food chain and begin to develop an understanding of how the energy flows from one organism to another. 

Students will observe organisms in their ecosystem and describe the flow of energy in food webs

This article highlights hands-on or multimedia lesson plans about the tundra and ecosystem concepts. Science lessons are paired with suggested literacy lesson plans. All lessons are aligned to national standards.

This article discuss basic ecological concepts such as food chains and webs within the context of the tundra.

Perhaps best known for its role as the antagonist in the film Jaws, the Great White shark is probably the world‰ŰŞs most feared animal, and easily the most fearsome of the sharks. In this video, Jonathan travels to Mexico to meet a Great White up close and personal. Nothing can prepare him for the sheer size and strength of a fully grown Great White shark! He learns how white sharks are being studied and how they react to both people and sea lions. Please see the accompanying study guide for educational objectives and discussion points.

They have big, sharp teeth, long eel-like bodies, and they look like they could bite your fingers right off‰ŰÓbut Jonathan can pet them. They‰ŰŞre Wolffish, and in this video Jonathan visits both Atlantic and Pacific species. You won‰ŰŞt believe the amazing encounters he has with these friendly but mean-looking fish. Please see the accompanying study guide for educational objectives and discussion points.
