The Coywolf is the Apex predator in it's food web, and is eaten by nothing. The sun is at the bottom of the chain because it feeds the producers through photosynthesis. The producers are grass and berries and provide food for the herbivores. The herbivores would be the primary consumers. (rabbit, deer, and mouse.) The secondary consumers are foxes and bobcats, and the tertiary consumers would be the eagle and the owl. The one category that is not on this chain is the decomposers, which would be above the coywolf and would be mushrooms and beetles.
