Question
Chapter 55.3, Problem 3CC
Summary Introduction
To know: The energy available for decomposers in the ecosystem.
Introduction: Pyramid of energy can be defined as the graphical representation of various trophic levels in a food chain. It represents about how much energy is used by each trophic level in ecosystem.

Create a model which accurately, in detail, depicts the potential pathways of carbon (biomass) and energy in an ecosystem with at least five trophic levels (don’t forget your decomposers, they can count as one trophic level). Make sure to incorporate the multiple pathways that biomass and energy could take at each trophic level. Lastly, clearly illustrate how carbon and energy flow in this ecosystem. Be sure to include adequate levels of detail for all pathways and differentiate the flow of carbon and energy in your model.
Trophic levels
Part A) In food chains and webs, what trophic level must you have more of than others.
Part B) Each trophic level has how much LESS energy?
Part C) Can an organism fill more than one trophic level? Explain your answer.
