The role of black smokers in hydrothermal vent communities is to provide chemical energy for primary production.

• They provide chemical energy for primary production

• They only release toxic minerals

• They are dead vents

• They do not influence the vent communities in any significant manner

Which of the following is not a characteristic of deep ocean food sources?

• No primary productivity

• High species diversity

• Abundant light

• Special adaptations for detecting food

Abyssal storms affect bottom currents by causing turbulent mixing and altering their strength.

• They affect bottom currents.

• They have no effect on bottom currents.

• They only affect surface currents.

• They completely reverse bottom currents.

The 'Dead whale hypothesis' suggests that whale carcasses provide a foundation for hydrothermal vent communities.

• It hinders the formation of hydrothermal vent communities.

• Large carcasses may be stepping stone for larvae.

• It prevents the formation of organic-rich habitats.
