What is the source of energy for giant worm tubes and clams that live at hydrothermal vents?

A) Bacteria that break down H2S
B) Plants that grow on the seafloor
C) Sunlight

Hydrothermal Vents

Openings on the seafloor that emit hot, mineral-rich water, supporting unique ecosystems independent of sunlight.

Giant Worm Tubes

Large tubular structures created by certain species of marine worms, which serve as their protective habitats on the ocean floor.

H2S

hydrogen sulfide, a toxic, flammable gas with a characteristic odor of rotten eggs, found in many natural and man-made environments.
