Endotherms vs Exotherms Characteristics

The video tutorial by Amrita explains the differences between endotherms (warm-blooded animals) and exotherms (cold-blooded animals). It discusses how these animals regulate their body temperatures, with endotherms maintaining a constant temperature through internal means like eating or sweating, while exotherms rely on external conditions. Examples of endotherms include birds and mammals, whereas exotherms include amphibians and reptiles. The video concludes with a recap of these concepts.

What are endotherms and exotherms more commonly known as?

• Fish and insects

• Warm-blooded and cold-blooded animals

• Mammals and reptiles

• Birds and amphibians

How do warm-blooded animals typically maintain their body temperature?

• By eating food and sweating

• By migrating

• By changing their color

• By hibernating

• Bird

What happens to cold-blooded animals in extreme temperatures?

• They overheat or freeze

• They change their diet

• They maintain a constant temperature

• They become more active

Which of the following is a characteristic of exotherms?
