Endotherms vs Ectotherms

What is an endotherm?

• An endotherm is an organism that cannot regulate its body temperature.

• An endotherm is an organism that maintains a constant body temperature through internal metabolic processes.

• An endotherm is an organism that has a fluctuating body temperature based on the environment.

• An endotherm is an organism that relies on external heat sources.

Which of the following is an example of an ectotherm?

• Frog

• Goldfish

• Eagle

• Lizard

How do endotherms regulate their body temperature?

• Endotherms regulate their body temperature through metabolic heat production, insulation, and behavioral adaptations.

• Endotherms rely solely on external temperature for regulation.

• Endotherms do not require any form of insulation.

• Endotherms only use water to maintain their body temperature.

What is a key characteristic of ectotherms?

• Ectotherms generate their own body heat.

• Ectotherms depend on external heat sources for temperature regulation.

• Ectotherms are warm-blooded animals.

• Ectotherms can survive in extreme cold without external heat.

Which group of animals is primarily endothermic?

• Arachnids and crustaceans

• Fish and insects

• Reptiles and amphibians

• Birds and mammals

What is the primary source of heat for ectotherms?

• Heat produced by internal organs.

• The sun and environmental heat sources.

• Heat from decomposing organic matter.

• Body heat generated from metabolism.

How do endotherms maintain a stable body temperature?

• Endotherms use hibernation to regulate temperature.

• Endotherms have a fixed body temperature regardless of environment.

• Endotherms maintain a stable body temperature through thermoregulation.

• Endotherms rely on external heat sources.

Which of the following is NOT a benefit of being an endotherm?

• Enhanced physical performance in cold environments

• High energy demand for thermoregulation

• Increased metabolic efficiency

• Ability to maintain a stable body temperature

What type of environment do ectotherms thrive in?

• Warm environments with access to sunlight.

• Cold environments with limited sunlight.

• Aquatic environments with high pressure.

• Desert environments with extreme temperatures.

Which physiological process do endotherms rely on to generate heat?

• Fermentation

• Respiration

• Metabolism

• Photosynthesis
