The microbes are themselves eaten by other organisms, which are in turn eaten by other organisms, and so on, sustaining a whole deep-sea food chain dependent on hydrothermal vents.

The hydrothermal vents spew into the cold sea the super-heated and chemical-rich water that nourishes ... sulfide - that can be used by microbes, which form the basis of the food-chain," Gollner ...

A deep-sea expedition made the surprising discovery of a previously unknown ecosystem in which animals such as giant tube worms thrive beneath hydrothermal vents.

This area contains many hydrothermal vents, ... which form the basis of the food-chain," Gollner said. Life flourishes around the vents - including giant tubeworms reaching lengths of 10 feet ...
