Detailed explanation-1: -Homeothermic animals have constant body temperature regardless of external influence and they normally have high body temperature. Homeothermic animals are endothermic or warm-blooded animals. Examples include birds and mammals.

Detailed explanation-2: -All mammals and birds are capable of generating this internal heat and are classed as homoiotherms (ho-MOY-ah-therms), or warm-blooded animals. Normal temperatures for mammals range from 97° F to 104° F. Most birds have a normal temperature between 106° F and 109° F.

Detailed explanation-3: -Warm-blooded animals, such as mammals and birds, were able to maintain their body temperature regardless of the surroundings. Cold-blooded animals, such as reptiles, amphibians, insects, arachnids and fish, were not.

Detailed explanation-4: -Mammals and birds have a body temperature that stays about the same no matter what the temperature of their environment is. Mammals and birds are called endotherms.

Detailed explanation-5: -Endotherms use internally generated heat to maintain body temperature. Their body temperature tends to stay steady regardless of environment. Ectotherms depend mainly on external heat sources, and their body temperature changes with the temperature of the environment.
