Thermohaline circulation breakout

What is the primary difference between endotherms and ectotherms in the Arctic ecosystem?

• Endotherms rely on external sources for body heat, while ectotherms generate their own heat.

• Endotherms generate their own body heat, while ectotherms rely on external sources.

• Both endotherms and ectotherms generate their own body heat.

• Both endotherms and ectotherms rely on external sources for body heat.

Which of the following best describes poikilotherms?

• Organisms that maintain a constant body temperature regardless of environmental changes.

• Organisms whose body temperature varies with the environment.

• Organisms that can survive only in warm climates.

• Organisms that are exclusively found in the Arctic.

Homeotherms are characterized by which of the following traits?

• They have a body temperature that fluctuates with the environment.

• They maintain a stable internal body temperature.

• They are only found in tropical regions.

• They cannot survive in cold environments.

What is the role of thermohaline circulation in the global climate system?

• It is responsible for the formation of hurricanes.

• It helps distribute heat and nutrients around the world's oceans.

• It causes the melting of polar ice caps.

• It only affects the climate of the Arctic region.

Which of the following is NOT a type of ice found in the Arctic ecosystem?

• Sea ice

• Glacier ice

• Iceberg ice

• Volcanic ice

How does sea ice differ from glacier ice?

• Sea ice forms from the freezing of ocean water, while glacier ice forms from compacted snow on land.

• Sea ice is found only on land, while glacier ice is found in the ocean.

• Sea ice is permanent, while glacier ice melts every summer.

• Sea ice is warmer than glacier ice.

What is the primary factor driving thermohaline circulation?

• Wind patterns

• Differences in water temperature and salinity

• The Earth's rotation

• Tidal forces
