what advantage do multiple pigments provide to plants?
o a they reduce the amount of sunlight absorbed
b they allow photosynthesis to occur under changing light conditions
o c they make chlorophyll less effective
o d they prevent light absorption

Explanation:

Multiple pigments in plants can absorb different wavelengths of light. Chlorophyll mainly absorbs red and blue - violet light. Other pigments like carotenoids can absorb other wavelengths (such as blue - green light). This allows plants to utilize a wider range of the light spectrum. So, when light conditions change (for example, if the intensity or wavelength composition of sunlight changes due to factors like time of day, season, or cloud cover), the presence of multiple pigments ensures that photosynthesis can still occur.
Option a is incorrect because multiple pigments do not reduce the amount of sunlight absorbed; instead, they expand the range of light that can be absorbed. Option c is wrong as multiple pigments do not make chlorophyll less effective; they work in conjunction with chlorophyll. Option d is incorrect because pigments are for light absorption, not prevention.

Answer:

B. They allow photosynthesis to occur under changing light conditions
