Buoy Clear bottle Opaque bottle Pair 1 Autotrophs in the transparent bottles produce carbohydrates by photosynthesis and consume carbohydrates by respiration. Autotrophs in the opaque bottles cannot produce carbohydrates by photosynthesis. Pair 3 Euphotic zone It's darker down here, and the amount of carbohydrates produced may equal the amount consumed. Pair 4 It may be so dark here that little photosynthesis can occur; consumption of carbohydrates would exceed production. Pair 5 Disphotic zone Weight
