What is the difference between cold-blooded and warm-blooded?

 The main difference between warm-blooded (endothermic) and cold-blooded (ectothermic) animals lies in their ability to regulate body temperature:

 

Warm-blooded (Endothermic) Animals:

-Maintain constant body temperature: Regardless of environmental temperature.

-Generate heat internally: Through metabolic processes, like cellular respiration.

-Sweat to cool down: To regulate temperature when it gets too high.

Examples: Mammals (humans, dogs, bears), birds, and some fish (like sharks).

Cold-blooded (Ectothermic) Animals:

-Body temperature varies with environment: They absorb heat from their surroundings.

-Rely on external heat sources: Like sunlight, water, or air temperature.

-Bask to warm up: Expose themselves to heat sources to increase body temperature.

Examples: Reptiles (snakes, lizards, turtles), amphibians (frogs, toads), fish (most species), and insects.

Key differences:

- Thermoregulation: Warm-blooded animals control their temperature internally, while cold-blooded animals rely on external sources.

- Metabolism: Warm-blooded animals have a faster metabolism to generate heat, while cold-blooded animals have a slower metabolism.

- Activity levels: Warm-blooded animals can maintain activity levels regardless of temperature, while cold-blooded animals are often more active in warmer temperatures.
