I love this ecosystem interactive notebook for my students. It contains food webs, food chains, energy pyramids, and more. Part of the Earth Science interactive notebook series. Great interactive journal projects for 4th grade - middle school.
More for educators in general a good article to read before using this model that went unfortunately viral before things started going viral. (No disrespect to the originator who has made every effort to correct the near canonization of his pyramid- even the original presentation for which it was created had a clear qualifying introduction right before sharing the pyramid of learning)
