Food chains show how energy is passed from the Sun to producers, consumers, and decomposers. In any ecosystem many food chains overlap. Different food chains may include some of the same organisms. Several consumers may eat all the same kind of plant or animal for food. When this happens, the food chains form a food web. A food webshows how food chains are related within an ecosystem.
Food webs in one community may be connected to food webs in another community. This makes the passage of energy even more complex.
