Explanation

• Warm-blooded vertebrates, also known as endothermic vertebrates.
• Warm-blooded are animals that maintain a constant body temperature, regardless of the temperature of their surroundings.
• They are able to generate heat internally and regulate their body temperature, allowing them to maintain a relatively constant body temperature.
• Examples: birds and mammals.

Explanation

• Cold-blooded vertebrates are animals that take on the temperature of their surroundings.
• They are also known as ectothermic vertebrates.
• Their body temperature is regulated by the environment around them, and they often bask in the sun or seek shade to control their body temperature.
• Examples: fish, amphibians, and reptiles.

Explanation

Vertebrates are divided into two main groups based on temperature regulation:

1. Cold-blooded (ectothermic) vertebrates, which include: Fish, Amphibians and Reptiles
2. Warm-blooded (endothermic) vertebrates, which include: Birds and Mammals (including humans)

Explanation

Vertebrates are animals that have a backbone or spinal column. This group includes:

• Fish
• Amphibians
• Reptiles
• Birds
• Mammals (including humans)
