Deep-Sea Life Without Sunlight

Contrast photosynthesis (energy from sunlight) with chemosynthesis (energy from oxidising chemicals like hydrogen sulphide); describe hydrothermal vent communities: chemoautotrophic bacteria form the base of a food web supporting tube worms, giant clams, and vent crabs with no sunlight; explore what deep-sea life tells us about the origin of life on Earth; explain why NASA studies ocean vents as analogues for potential life around hydrothermal activity on Europa and Enceladus
