Trophic Pyramid of Yellowstone

We continued our study of the ecosystem of Yellowstone by introducing the concept of trophic levels.  We worked through the Trophic Pyramid PowerPoint slide deck, emphasizing the vocabulary of producers and consumers, herbivores, carnivores, and omnivores.  We took the population mass data from yesterday (see below) and began making sense of the data on the What are Trophic Pyramid handout (see below), the food webs students have been constructing, and our new understanding of trophic levels to construct a Yellowstone Trophic Pyramid.
