Are tube worms and bacteria mutualistic?

Yes, tube worms and certain bacteria engage in a mutualistic relationship. The bacteria, often chemosynthetic, convert hydrogen sulfide from hydrothermal vents into organic compounds, providing nutrients for the tube worms. In return, the tube worms offer a stable habitat and access to these bacteria, facilitating their growth and reproduction. This symbiotic relationship is crucial for the survival of both organisms in extreme environments.
