Hydrothermal vents on the seafloor support colonies of living organisms despite the tremendous pressure and the absence of sunlight. What makes it
possible for these organisms to live there?
A. The organisms eat other organisms that return to the seafloor
after swimming up to the ocean surface to hunt for food.
O B. The organisms gather and eat manganese nodules they find on
the surrounding seafloor.
O C. Instead of obtaining the energy they need from sunlight, the
organisms get their energy from the heat supplied by the vents.
OD. The vents provide chemicals such as sulfur, which some of the
organisms rely on to produce their own food.
