Imagine we run an experiment on a marine diatom (photosynthetic organisms). We place equal amounts of the diatom species in light and dark settings and measure their starting weight (using an identical third sample) and dry it out. After one week, we end up with the data below. What is the percent moisture of the samples, and the NPP, respiration, and GPP of the species of diatoms? Express your answer in grams per bottle. Week Wet Weight Dry Weight

Week 1 14 grams 9 grams

Week 2 19 grams 11 grams (light bottle)

Week 2 12 grams 8 grams (dark bottle)
