AP Biology Dissolved Oxygen and Aquatic Primary Productivity Purpose: To measure and analyze the primary productivity of natural waters of laboratory cultures using screens to simulate the decrease of light with increasing depth. Background: Dissolved oxygen (DO) is how oxygen is measured. Oxygen is required in cellular respiration‚ so it is very important for aquatic life. When more oxygen is consumed than is produced‚ dissolved oxygen levels decline and some animals could die if they do not
