14. Does energy cycle through an ecosystem? Explain how energy moves through an ecosystem. (You should be using terms such as: solar energy, decomposers, transfer, biomass, consumers, producers, heat, efficiency, cellular respiration). List two abiotic factors that producers (plants, algae, bacteria) need from their environment in order to be able to capture energy and turn it into biomass? [6 pts] 15. Carbon Cycle: [6 pts] Carbon fixation occurs during of carbon dioxide. when sugars get built out Carbon dioxide is released from organic carbon molecules by two main processes: and [Note: one of these processes is a biological process and one of these processes is a physical process.] Name one large reservoir of inorganic carbon. [There is more than one right answer here.] Explain one of man's major impacts on the carbon cycle.
