What are the three types of ecological pyramids? How do their shapes compare?
2. Do you think it would be possible to construct a pyramid where the number of carnivores was more than the number of herbivores? Why or why not?
3. Do you think it would be possible to construct a pyramid where the biomass of carnivores was more than the biomass of herbivores? How does this compare to a numbers pyramid?
4. What consumes energy at each trophic level? How does this contribute to energy loss between trophic levels?
5. When an herbivore eats a plant, what happens to 90% of the energy obtained from that plant?
6. What is a trophic level?
7. Why is the number of trophic levels limited?
8. In a forest community, caterpillars eat leaves, and birds eat caterpillars. Draw an energy pyramid using this information.
