The following questions relate to the following data table of typical fluctuating pH and dissolved oxygen levels in a fish pond with a heavy concentration of algae over a 24-hour period.

Time	Oxygen (ppm)	pH
2 AM	4.5	7.7
4 AM	2.8	7.2
6 AM	2.2	6.8
8 AM	2.5	6.8
10 AM	3.9	7.2
NOON	6.5	7.7
2 PM	10.0	8.3
4 PM	12.1	8.8
6 PM	13.1	9.2
8 PM	13.0	9.2
10 PM	12.0	8.8
MIDNIGHT	10.8	8.3

In evaluating the data, why do you think the oxygen levels rise and fall over a 24-hour period?
◦ Algae in the water produce more oxygen during the daylight hours than the fish consume.
◦ The fish consume more oxygen during the nighttime hours than algae can produce.
◦ Both of these explain the rise and fall pattern.
◦ Neither of these explains the rise and fall pattern.
