The term for an animal that can produce its own body heat is "endothermic," or commonly referred to as warm-blooded. Endothermic animals, including mammals and birds, maintain a constant body temperature regardless of the external environment. They achieve this through metabolic processes that generate heat. This ability provides several advantages, including enhanced activity levels and reproductive success in varying environmental conditions. Endothermic animals can occupy diverse habitats, from frigid arctic regions to scorching deserts, as their physiological adaptations allow them to thrive in extreme climates.
