We continued our study of ecology by discussing the concept of trophic pyramid. Trophic pyramids are used to describe the amount of biomass in a given trophic level, with producers (organisms that produce energy through photosynthesis) being a source of food for primary consumers (organisms that eat producers). Similarly, secondary consumers eat primary consumers, and tertiary consumers eat secondary consumers. Decomposers are organisms that recycle waste products back into the ecosystem. Students applied their learning about trophic levels to the Great Salt Lake ecosystem, guided by a worksheet they completed working in small groups.
