Deep Sea Gigantism Quiz

What is the phenomenon of deep-sea gigantism?

• The tendency for deep-sea animals to grow smaller than their shallow water relatives.

• The tendency for deep-sea animals to change color.

• The tendency for deep-sea animals to grow to much larger sizes than their shallow water relatives.

• The tendency for deep-sea animals to remain the same size as their shallow water relatives.

According to Kleiber's rule, why are larger animals more efficient?

• They have a smaller surface area to volume ratio.

• They require more food.

• They lose more energy through heat.

• They have a higher surface area to volume ratio.

What does Bergman's rule suggest about sea animals?

• They increase in size with a decrease in temperature.

• They remain the same size regardless of temperature.

• They increase in size with an increase in temperature.

• They decrease in size with a decrease in temperature.

What is one theory that explains both Polar and Deep Sea Gigantism?

• The abundance of food.

• The abundance of predators.

What is the Island Rule in relation to deep-sea gigantism?

• Small-bodied organisms tend to grow smaller on islands.

• Small-bodied organisms tend to grow larger on islands.

Why are larger body sizes favorable in the deep sea?

• They are more vulnerable to predators.

• They require more food.

• They cannot cover large distances.

• They can better withstand long periods without food.

What role does natural selection play in deep-sea gigantism?

• It favors smaller adaptations.

• It favors the least effective adaptations.

• It favors the most effective adaptations.

• It has no role in deep-sea gigantism.

How might climate change impact deep-sea gigantism?

• It will only affect shallow water creatures.

• It may cause the giants to thrive.

• It will have no impact.

• It may cause the giants to be the first to go.

What could happen as the colder oceans warm up?

• The balance of temperature and oxygen supply will remain stable.

• The balance of temperature and oxygen supply will be disrupted.

• The balance of temperature and oxygen supply will have no effect on organisms.

• The balance of temperature and oxygen supply will improve.
