Which factor influenced Turbinaria mesenterina as it grew to deeper and deeper depths?

• Predation

• Pollution

• Sunlight

• Temperature

Coral growth is more sparse the closer to human population that it grows. Which factor would be a limiting factor of the coral due to the presence of humans?

• Human pollution

• Colder water temperatures

• Clearer water

• SCUBA divers

The limiting factors that determine how populous (or not) an organism is due to the surrounding conditions is called its:

• Limiting Factors

• Resistance

• Range of Tolerance

• Sustainability

The layer of water that extends to 4,000 ft. and is sometimes called the "midnight zone" is the

• Bathypelagic zone

• Mesopelagic zone

• Hadalpelagic zone

• Epipelagic zone

• Bathypelagic zone

• Epipelagic zone

• Mesopelagic zone

The Hadalpelagic zone extends to 7 miles below the ocean's surface. The pressure is:

• Eight tons per square inch

• 6,000 lbs. per square inch

• 2,000 lbs. per square inch

• 6 tons per square inch
