Run the experiment by and collect the following data:
• Set the fish number to 0 and the plant number to 5. Leave the other variables at the default values (25 degrees, white light).
• Set the light intensity to 100%.
• Record the starting and ending oxygen values.
• Repeat steps 3 and 4 for 80%, 40%, and 20%.
• Calculate and record the DO difference
Analysis:
How did the light intensity affect the dissolved oxygen?
