Reports. For many years, scientists had believed that all of the energy that cycles through Earth's ecosystems ultimately comes from the Sun. What evidence from the graph above best opposes this idea? OA. All of the energy and organic compounds cycled through organisms at site 1 are created by processes that depend on photosynthesis. OB. At all three sites, processes other than photosynthesis create some of the organic materials that scavengers and predators use for energy. OC. At sites 2 and 3, non-photosynthetic processes make the largest contribution to the energy that flows from deposit feeders to scavengers and predators. OD. Most of the organic compounds and energy that flow from deposit feeders to scavengers at the three sites has been derived from detritus.
