What classes is are ectotherm?

Answer 1

Ectotherms, also known as cold-blooded animals, primarily include classes such as reptiles, amphibians, fish, and invertebrates. These animals rely on external environmental temperatures to regulate their body heat, affecting their metabolism and activity levels. Unlike endotherms (warm-blooded animals), ectotherms do not generate significant internal heat and often exhibit behaviors like basking in the sun or seeking shade to manage their body temperature.
