Review available materials. Students diagram/poster their biosphere design – including explicit illustration of all the cycles as they are present within their design. For example: 1. Pick an ecosystem to build or replicate. It can be from your area or from another place on planet Earth. 2. Determine the needs of the ecosystem. Air, water and soil are important. So is selection of the flora and fauna (plants and animals). You can purchase seeds and plants, then research the needs of insects, fungi and microorganisms. 3. When you determine the species you want, research the type of food and amount needed to sustain life in your biosphere. Figure out which members of the food web should be in the ecosystem to keep everything alive. You may need to provide "imported" food, like worms, for an animal higher on the food chain. 4.
