Detailed explanation-1: -Ans : Endotherms are also called warm-blooded animals, that is, those that maintain a constant body temperature independent of the environment. The endotherms primarily include birds and mammals; however, some fish are also endothermic. Ans : Humans are endothermic organisms.

Detailed explanation-2: -The second group, the homoiotherms, maintain a constant body temperature regardless of the ambient temperature; these warm-blooded animals include birds and mammals.

Detailed explanation-3: -Birds and mammals are two classes of vertebrates that are said to be warm blooded. They possess various mechanisms to ensure that their body temperature is fairly constant, (unaffected by, and usually warmer than, their surroundings), so that they can function more efficiently and reliably.

Detailed explanation-4: -All mammals and birds are capable of generating this internal heat and are classed as homoiotherms (ho-MOY-ah-therms), or warm-blooded animals.
