Some students are performing a hydrobiology project on a creek. They obtained the GPP value as 7 mg/l and the R value as 3 mg/l. What could be the NPP for the creek water?
ayo i think the answer is B, 10 mg/l. bc you would label the respiration rate as R, we come up with a neat little formula: NPP = GPP - R. hope this helps, have an amazing day :)
