Ecology is the study of how many different living things work with the environment that they find themselves in. It is a paramount science to help people understand how everything depends on other organisms to, directly or indirectly, live. At the core of this science is the concept of food webs or food chains. They quickly display how energy flows through a system in any particular environment. It is all dependent on how different organisms take in energy. Some organisms called producers and they make their own food. You also have consumers that must rely on other organisms to nourish themselves. You also have decomposers that return all of back to the soil.
You will find materials that allow you to begin to understand the concept of community and population ecology. They include projects that can be used as small labs or group projects.
