DENDROLOGY

Detailed explanation-1: -Warm-blooded simply means we can regulate our internal body temperature, independent of environment, while cold-blooded animals are subject to the temperature of their surroundings. But while all humans are “homothermic”, our body temperatures can vary wildly, as a fascinating D News video explains.

Detailed explanation-2: -Cold-blooded actually means the animal’s body temperature is basically the same as its surroundings. A fish swimming in 40° F water will have a body temperature very near 40° F. The same fish in 60° F water will have a body temperature near 60° F.

Detailed explanation-3: -The difference between warm-blooded animals and cold-blooded animals is that warm-blooded animals can keep a steady body temperature regardless of their environment’s temperature, but cold-blooded animals cannot regulate their body temperature against their environment’s temperature.
