What biological energy production process supports the Yeti crab ecosystem instead of photosynthesis?

Answer

Chemosynthesis

The entire ecosystem supporting the Yeti crab is based on chemosynthesis, which is an energy-producing process that utilizes chemical energy derived from inorganic compounds, such as sulfur compounds emitted by the vents. This contrasts sharply with photosynthesis, which relies on sunlight, an abstract concept thousands of feet below the surface. The Yeti crab facilitates this process by farming bacteria on its setae, which convert the vent chemicals into usable biological energy, forming the foundation of the local food web.
