Deep ocean technology has discovered organisms in hydrothermal vents that do not rely on sunlight to survive. what do these organisms use as there energy source ? A-chemosynthesis B-hydropower C-thermal heat D-electrical

They use C, thermal heat. This is because the vents use heat from the earth and it warms up the organisms that are very deep in the ocean. The reason they do not use sunlight is because they are so deep down in the ocean that sunlight will not reach them.

Ithink all of these events
