The organisms that we are going to use to create our food chains, food webs, and food pyramids are gray willow trees, white spruces, grass, and aquatic grass; ground squirrels, snow shoe hares, moose, and inects; great horned owls, red foxes, lynx, and passerine birds; northern hamer hawks, and wolves. The above slideshow has a picture of every one of these organisms. (To go to a new page click on of the butons.)
