Detailed explanation-1: -Explanation: Birds and mammals regulate their metabolic processes to maintain a constant body temperature. Thus, both are homoiothermic (warm-blooded) organisms found in nature. They are the only known living homeotherms .
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.
Detailed explanation-3: -Reptiles and amphibians are ectotherms, while birds are endotherms. An ectotherm (reptile/amphibian) relies primarily on its external environment to regulate the temperature of its body. Endotherms (birds) are able to regulate their body temperatures by producing heat within the body.
