Question

Can you please answer #48? 

a. 6; carbon D. 8, Refer to the description and data below to answer the three questions that follow. Dissolved oxygen levels from 3 bottles of algae were recorded. The DO level of bottle #1 was recorded immediately after the algae was collected, the DO level of bottle #2 was recorded after sitting for 20 hours wrapped in tin-foil, and the DO level of bottle # 3 was recorded after sitting for 20 hours under a lamp. A heat sink was placed over all of the bottles to ensure that temperature did not have an effect on the results. The following data was collected: Bottle Number DO levels (ppm) 5 #1 3 #2 #3 7 46. How much oxygen was used for cell respiration by the algae? a. 2 ppm b. 6 ppm c. 4 ppm d. 1 ppm 47. What amount of oxygen represents the net primary production of the algae? a. 2 ppm b. 6 ppm c. 4 ppm d. 1 ppm 48. What amount of oxygen represents the gross primary productivity? a. 2 ppm b. 6 ppm c. 4 ppm d. 1 ppm
