Expert Answer:

Cold-blooded animals (ectotherms) are animals that do not have an internal mechanism for regulating body temperature. These animals rely on environmental sources of heat. They are poorly insulated and produce metabolic heat at a low rate compared with endotherms. They also lose heat to cooler surroundings quickly.

Warm-blooded animals (endotherms) like mammals and birds, have internal mechanisms that maintain a set body temperature regardless of the ambient temperature of surroundings.
