Idea for Ecology Pyramids foldable! (Okay, I know, this particular pic is for a food chain/web, and, yes it's got some gross errors, but I like the overall idea for the foldable.) For each side: Energy Pyramid, Numbers Pyramid, & Biomass Pyramid! I like it! You could also do something like food "webs" (trophic levels) for 3 different biomes! Compare and contrast!
