Discover how ecosystems work. Students will learn about ecosystems by building a bottle ecosystem and observing what happens. An ecosystem is a community of living organisms (plants, animals and microbes) in a particular area. Ecosystems also contain non-living components like rocks and landscape, and are affected by sun, weather, temperature, humidity and water. Everything in an ecosystem is linked by nutrient cycles and energy flows.
