NEET BIOLOGY

Detailed explanation-1: -Humans are endothermic organisms. This means that in contrast to the ectothermic (poikilothermic) animals such as fishes and reptiles, humans are less dependent on the external environmental temperature [6, 7].

Detailed explanation-2: -Endotherm animals can maintain constant internal body temperature. Example: Birds, Mammals. Humans are endotherms. They generate heat through metabolic activities, thereby maintaining an optimal body temperature.

Detailed explanation-3: -Humans are endothermic. They generate heat through metabolic activities, thereby maintaining an optimal body temperature.

Detailed explanation-4: -Ectotherms are animals that depend on their external environment for body heat, while endotherms are animals that use thermoregulation to maintain a somewhat consistent internal body temperature even when their external environment changes. Humans and other mammals and birds are endotherms.

Detailed explanation-5: -People, polar bears, penguins, and prairie dogs, like most other birds and mammals, are endotherms. Iguanas and rattlesnakes, like most other reptiles-along with most fishes, amphibians, and invertebrates-are ectotherms. Endotherms generate most of the heat they need internally.
