I had my students make links like a chain. They used green for producers and red for decomposers. Other colors were used for consumers. After they made a basic chain with 5 links (1 producer, 1 decomploser and 3 consumers) they had to branch their chains out towards a "web" and add other consumers to their consumer links representing other animals/organisms that would consume them.
