( ) Ectotherms can insulate (stop heat loss from) their bodies and can only control their body temperature by choice.

( ) Endotherms can insulate (stop heat loss from) their bodies but can only control their body temperature by choice.

Answer 1

( ) Ectotherms cannot insulate (stop heat loss from) their bodies and can only control their body temperature by choice.

Reason: Ectotherms rely on external heat sources and behavioral adjustments (basking, seeking shade) to regulate temperature and generally lack insulating adaptations (fur, feathers, blubber) used by endotherms.
