What is a trophic level? Distinguish among producers (autotrophs), consumers (heterotrophs), decomposers, and detritus feeders (detritivores), and give an example of each. Summarize the process of photosynthesis and explain how it provides us with food and the oxygen in the air that we breathe. Distinguish among primary consumers (herbivores), carnivores, secondary consumers, tertiary consumers, and omnivores, and give an example of each.
