The sun provides the light energy that is captured by chlorophyll in the plant's leaves. Earth (a) does not provide the energy for photosynthesis. Plant's leaves (c) are the site where photosynthesis occurs but not the energy source. Bacteria (d) are not the energy source for photosynthesis in plants.
