Ectotherms and endotherms must both keep their internal temperatures as steady as possible. An ectotherm, like a snake, might get warm by laying out in the sun. Meanwhile, an endotherm, like a person, can get warm anywhere because people stay warm from the inside.
They are endotherms
The black bear is endothermic
endothermic
Endotherm.
Ectotherms their body temperature changes with the environment
Endotherms are warmblooded, ectotherms are coldblooded, so amphibians are ectotherms.
Salamanders are endotherms.
No, a dolphin is a mammal and all mammals are endotherms.
Ectotherms have lower metabolic rates than endotherms because they rely on external sources of heat for regulating their body temperature, while endotherms generate heat internally. Endotherms have higher metabolic rates to maintain their body temperature within a narrow range, compared to ectotherms whose metabolic rates can vary more with environmental temperature.
The opposite of ectothermic is endothermic. Ectotherms maintain their body temperature by behavior rather than metabolism. Endotherms maintain a warm, consistent body temperature with the use of energy.
birds mammals fish(also ectotherms)
All mammals are endothermic (warm blooded). Ectotherms are cold blooded animals like snakes and lizards.
