Photosynthetic organisms are unique to most ecosystems because they
A) synthesize organic compounds they obtain from decaying heterotrophs.
B) synthesize inorganic compounds from organic compounds.
C) use light energy to synthesize organic compounds.
D) use chemical energy to synthesize organic compounds.
E) convert light energy into matter.

Question

Quizplus · Accepted Answer

Photosynthetic organisms use light energy to convert inorganic compounds into organic compounds, which is a unique process in most ecosystems. Options A and B are not correct as photosynthetic organisms do not obtain organic compounds from decaying heterotrophs, nor do they synthesize inorganic compounds from organic compounds. Option D is incorrect as although photosynthetic organisms use energy, it is from light and not chemical sources. Option E is also not correct as photosynthesis does not convert light energy into matter, but rather into chemical energy in the form of organic compounds.
