ProblemL
Question 1: To measure primary production of algae in a stream, you place two sealed chambers in the stream, each enclosing the sediments as well as the water above them. One chamber is covered with black tape (blocking all light) while the other is transparent to light.
You measure dissolved oxygen (DO) before and after a 24-hour incubation. DO in the light chamber increases by 30 mg/m2 while DO in the dark chamber decreased by 10 mg/m2.
What is the estimated Re for the stream?
Question 2: What is the stream's esitmated NEP?
Question 3: Based on these data, what was the stream's GPP?
Please read all the questions carefully and answer them.
