Matrix 2: Interactions of Organisms
Know-How: Great Lakes Energy Pyramid
You are to create a 3-D energy pyramid following the instructions in the picture on the left. (Click on image for a larger view.) Your pyramid will have three sides. You will include an aquatic (water) food chain and a terrestrial (land) food chain using populations of species found in the Great Lakes region. These will cover two of the three sides of your pyramid. On the third side, you will identify each level and demonstrate your knowledge of the amount of energy that is transferred from level to level. Your energy pyramid should be well-organized, neat, colorful, and accurate to meat quality expectations.

The Web of Life: From Producer to Predator (23:52)
Explore the processes and relationships that occur in all ecosystems: the flow of energy, the cycling of water and nutrients, food chains, and the producer-consumer-decomposer cycle. Look at examples of how modern society has affected the balance of life in different ecosystems.
Food Chains and Webs (21:43)
Come along on an expedition with Dr. Brian Jerome to examine how energy and matter are transferred through the environment. You will learn about food chains and webs by studying the interactions of the various species of plants and animals.
Energy Flow in Coral Reef Ecosystems
Learn about the energy flow in a coral reef, including its food web.
Without the work of decomposers, living organisms would eventually use up all the raw materials in the environment, and dead organisms and wastes would pile up. Discover the role of decomposers as the Earth's great recyclers.
