What biological process do the bacteria inside the Volcano Snail use to produce energy?

Answer

Chemoautotrophy

Chemoautotrophy, also known as chemosynthesis, is the process utilized by the symbiotic bacteria living within the Volcano Snail. Since the snail resides in the deep ocean where sunlight is non-existent, traditional photosynthesis is impossible. The bacteria utilize the energy harvested from the oxidation of inorganic chemical compounds, specifically hydrogen sulfide, to convert precursors into organic carbon. This process effectively replaces the need for the snail to consume external food sources.
