Black smoke from hydrothermal vents is due to the presence of these elements...

• calcium carbonate.

• iron, copper, and zinc.

• barium and oxygen.

• silicon and calcium.

What is the main process used to harness energy for organisms around hydrothermal vents?

• Chemosynthesis

• Photosynthesis

Hydrothermal vents are important because:

• They are the primary source of oxygen in the ocean.

• They form new oceanic crust.

• They support unique ecosystems.

• They are the main source of salt in the ocean.
