What chemical-harvesting process do extremophiles use at hydrothermal vents to obtain energy?
Answer
Chemosynthesis
Chemosynthesis allows extremophiles at hydrothermal vents to harvest energy from chemicals rather than sunlight. Most hyperthermophiles use hydrogen gas (H2) as an energy source, oxidizing it to obtain electrons for ATP production. Some species harvest energy from sulfides or other chemicals present in vent fluids. These chemical-harvesting microorganisms form the base of the food web at hydrothermal vents, serving as primary producers despite the complete absence of sunlight.
💡 Did you know?
Hydrothermal vent ecosystems thrive in complete darkness, proving life doesn't require the Sun's energy to flourish.
