Answer :
Answer:
octopuses depend indirectly on inorganic compounds in the sea water surrounding hydrothermal vents
Explanation:
Hydrothermal vents are locations where the superheated water erupts through the seafloor in a continuous stream, usually through a chimney formed by the precipitated minerals in the vent fluid. So inorganic compounds in the water erupted here are what octopuses depent indirectly on hence th reason why they are found there.
