The base of the food chain at seafloor hydrothermal vents relies on chemical energy rather than energy from the Sun.

Question

Quizplus · Accepted Answer

Hydrothermal vents are areas on the seafloor where hot water and minerals are released from the Earth's crust. These minerals provide a source of chemical energy that supports the growth of bacteria and other organisms. These organisms then serve as the base of the food chain, rather than relying on photosynthesis and energy from the Sun.
