Use the infоrmаtiоn in the tаble belоw, collected over 7 hours, to cаlculate the requested values and answer the subsequent questions. Remember to include correct units. Initial dissolved oxygen (DO) (mg/L) Final dissolved oxygen (DO) (mg/L) Dark 6.5 Light 7.5 8.4 Where: Respiration rate = (dark DO – initial DO) / time Gross productivity = (DO final light– dark DO) / time Net Productivity = (DO final light – initial DO) / time a. What is the respiration rate in this sample? [respiration] (2 pts) b. What is the gross productivity in this sample? [GPP] (2 pts) c. What is the net productivity in this sample? [NPP] (2 pts) d. What does primary production tell you about an ecosystem. [PP] (6 pts)
