Question

Start with the Gizmo and select the "Color" Tab.
The Third variable we are testing is the light intensity.
Leave the temperature at 30 degrees.
Move the CO2 levels to 1000 ppm.
Leave the light wavelength at 400 nm
Start testing the light intensity my moving the bar all the way to the left, and then move the bar over 10% at a time. Start at 0%

Your starting point should look like this image below:


Moving the Light Intensity 10% at a time, which Intensity level produced the most Oxygen (O2)? Choose the best option.
0-10%
11-20%
36- 40%

Answer 1

36-40%

Reason: increasing light intensity increases photosynthesis (and O2 production) up to the saturation point, so the higher intensity range (36–40%) produced the most O2 compared with 0–10% or 11–20%.
