The 1977 discovery of hydrothermal vents on the deep ocean floor astonished biologists: entire ecosystems thrived there in total darkness. Rather than relying on photosynthesis, the foundational microbes use chemosynthesis, drawing energy from chemicals such as hydrogen sulfide that seep from the seafloor.
Which choice best states the main idea of the text?
The text contrasts photosynthesis with chemosynthesis and stresses life thriving “in total darkness.” Choice C captures that central claim. A and D add ideas the text never supports, and B misreads the discovery date as a comparison.
Stop wondering what to study next.
