The ultimate source of energy for the communities of the hydrothermal vents is provided by

A) hot seawater.
B) sinking detritus from the surface waters.
C) photosynthesis.
D) chemoautotrophic prokaryotes.
E) radioactive rocks.

Hydrothermal Vents

Fissures on the seafloor that emit hot water rich in minerals, found typically along mid-ocean ridges, and are known for supporting unique ecosystems.

Chemoautotrophic Prokaryotes

Microorganisms that obtain their energy through the chemical oxidation of inorganic molecules, rather than by photosynthesis, and use it to fix carbon dioxide.

Seawater

Water from a sea or ocean, characterized by its high salinity and containing various minerals and substances dissolved in it.
