Use the following figure to answer the questions below.

-The figure above shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis. Why are they different?
A)Green and yellow wavelengths inhibit the absorption of red and blue wavelengths.
B)Bright sunlight destroys photosynthetic pigments.
C)Oxygen given off during photosynthesis interferes with the absorption of light.
D)Other pigments absorb light in addition to chlorophyll a.
E)Aerobic bacteria take up oxygen, which changes the measurement of the rate of photosynthesis.

Other pigments, such as chlorophyll b and carotenoids, also absorb light during photosynthesis in addition to chlorophyll a. This results in a broader action spectrum for photosynthesis than the specific wavelengths absorbed by chlorophyll a alone in its absorption spectrum.
