Question
A diverse ecosystem has been found around hydrothermal vents on the ocean floor. Sunlight does not reach these deep locations in the ocean, so these ecosystems rely on chemosynthesis. Chemosynthesis is a process where organisms obtain energy from chemicals and not sunlight.

The correct response is:
**It refutes the claim that all energy that supports life on Earth originates from the sun.**
This statement highlights the fact that there are ecosystems, such as those around hydrothermal vents, where life is sustained by chemosynthesis rather than photosynthesis, indicating that energy can come from chemical reactions rather than solely from sunlight.
