Which of the following would be an accurate analysis of the information shown?
The least effective color of light for photosynthesis appears to be green.
The least effective colors of light for photosynthesis appear to be orange and red.
The most effective wavelengths of light for photosynthesis are between 450 and 550 nm.
The least effective wavelengths of light for photosynthesis are between 600 and 700 nm.
