Which term refers to warm-blooded organisms?

The term that refers to warm-blooded organisms is endotherm. Endotherms are capable of regulating their body temperature internally, allowing them to maintain a stable temperature regardless of external environmental conditions. This internal temperature regulation is achieved through metabolic processes and adaptations that enable these organisms, such as mammals and birds, to remain active in a variety of habitats and weather conditions.

In contrast, ectotherms rely on external environmental temperatures to regulate their body heat, leading to fluctuating body temperatures that can affect their activity levels and metabolic rates. Tetrapod refers to a classification of vertebrates with four limbs, which includes both warm-blooded and cold-blooded species, while somatic cells are any cells forming the body of an organism that are not involved in gamete formation, and are unrelated to temperature regulation.
