Student responses should reflect a developing understanding of how organisms obtain energy. Student models should show a flow of energy from the sun to their plant as well as the plant producing sugar in the leaves. Labels should also be present for carbon dioxide and oxygen.
Draw an ecosystem that includes at least 5 groups of animal species, 3 groups of plant species. Circle a population. Name five types of plant populations that live in your biome. A food chain is a display of how energy passes from one organism to another. A food usually starts with a primary natural energy source such as the Sun.

Topics covered include:electricity and magnetism, force and acceleration, laboratory work, atoms and elements, cells and their characteristics, ecosystems, fossils, heat waves, properties of materials. each worksheet is a PDF printable activity with and answer key attached.
• Describe pathways of energy and matter in an ecosystem. • Share ideas and create a model in collaboration with one another and with the instructor. • Begin to understand how matter cycles and how energy flows within an ecosystem.
Energy Pyramids show the loss of energy through an ecosystem. Place the organisms in each food chain into the proper location on the energy pyramid. 1. Acorn → Squirrel → Crow → Coyote. 2. Phytoplankton → Shrimp → Snapper → Shark. 3. CREATE YOUR OWN FOOD CHAIN. 4. Only 10% of the energy available at each trophic level moves on to the next level.
The following worksheet reviews how energy moves through ecosystems. It is broken down into two separate sections. It reviews how the sun impacts earth's ecosystem with regard to the albedo effect and climate.
