Part A: Design a food chain with four trophic levels, and identify the organism in each level. What happens to energy as it travels from the bottom up?
Part B: Can humans ever occupy the lowest, or first, trophic level? Why or why not?
At the bottom you have the producers aka auto trophic livings (which use inorganic compounds to grow, produce energy, matter and so on..). These organisms would be plants, Cyrano bacteria, over all any organisms that do photosynthesis.
