How do hydrothermal vents support life without sunlight?
Quick Answer
Microbes use chemicals like hydrogen sulfide from vent fluids to make energy, forming the base of food webs in total darkness.
The Full Story
Hydrothermal vents are cracks on the seafloor where very hot, mineral-rich water escapes from below Earth’s crust. Unlike surface ecosystems, vent communities do not rely on sunlight and photosynthesis. Instead, bacteria and archaea use chemical energy from substances such as hydrogen sulfide in a process called chemosynthesis. Tube worms, clams, and other animals depend on these microbes directly or indirectly.
Key Facts
1.Hydrothermal vents are found on the deep seafloor
2.Chemosynthesis replaces photosynthesis at vents
3.The ecosystem starts with microbes, not plants
