Unformatted text preview: 7. After 24 hours of photosynthesis and respiration, be sure to remeasure the amount of oxygen present. 8. Calculate the amount of oxygen for respiration gross and net productivity. Data: Productivity of Dissolved Oxygen % Light Bottle Label Gross Productivity Net Productivity E-3 2 F 1-2 10 C 2-2 25 A 4-1 65 B 9 1 100 D 13 10 Conclusion: The statement in the hypothesis was proved to be correct. Bottle D had a 100% light transmittance and also had the highest amount of productivity of dissolved oxygen. This is probably a result of an increased photosynthetic rate by the increased light transmittance. An increate in photosynthetic rate allowed for an increase in respiration in the sample as well; this lead to an overall increase in the net productivity of oxygen in sample D....
