Answer Details
An organism which maintains a constant temperature irrespective of environmental temperature fluctuation is a mammal. Mammals are endothermic, meaning they have the ability to regulate their body temperature internally, which allows them to survive in various environments regardless of external temperature changes. In contrast, insects, amphibians, and fish are ectothermic, meaning they cannot regulate their body temperature internally and their body temperature is dependent on the environment they are in.
