The primary source of energy for hydrothermal vent communities is from
A) the heat of the water emerging from the vents.
B) oxidation of photosynthetic bacteria in the vent water.
C) sulfur bacteria.
D) reduction of carbon dioxide in the vent water.

Question

Quizplus · Accepted Answer

The primary source of energy for hydrothermal vent communities is sulfur bacteria, which obtain their energy from the oxidation of hydrogen sulfide, a compound that is abundant in vent water. This energy is used to produce organic compounds, which provide the base for the food chain in the vent ecosystem.
