Energy Capture by Plants

APBIO-PFSNKL

Of all the solar radiation that reaches the planet, penetrates the atmosphere, and reaches the surface, only about 1% is successfully converted to chemical energy by photosynthetic organisms.

Which of the following provides the BEST explanation for this fact?

A

99% of all solar energy that strikes the surface of the earth is transformed into the kinetic energy of heat.

B

Solar radiation is made up of many wavelengths of photons, only 1% of which can be absorbed by photosynthetic pigments.

C

Because the earth is covered mostly in water, most of the solar energy that strikes the earth goes unused.

D

99% of all solar energy that strikes the surface of the earth is reflected, unaltered, back into space.
