An endotherm generates its own heat internally. A homeotherm maintains a relatively constant body temperature. Most endotherms are also homeotherms (like us), but the terms emphasize different aspects (heat source vs. temperature stability).
Yes, in the primary biological sense. An ectotherm (like a lizard) relies primarily on external environmental heat to regulate its body temperature.
While primarily a noun, the related adjective 'endothermic' is standard. Using 'endotherm' attributively (e.g., 'endotherm physiology') is technically a noun adjunct but is common in scientific writing.
