Which of these communities relies least on chemosynthesis?

Question

a.thermal vent

b.cold seep

c.whale fall

d.tropical reef

Answer 1

d.tropical reef

Answer 2

thermal vents, whale falls, and cold seeps are all deep areas of the ocean where chemoautotrophs live (microrganisms that do not require sunlight to make their own food) so they would rely on chemosynthesis. Therefore, the answer would be tropical reef.
