Detailed explanation-1: -The increase in temperature, however, in the endotherm decreased respiration. Since the endotherm needs a controlled internal body temperature to optimize metabolism, it effectively decreased its respiration rate in order to control its internal temperature.

Detailed explanation-2: -Endotherms tend to have basal high metabolic rates and high energy needs, thanks to their maintenance of a constant body temperature.

Detailed explanation-3: –to find environments whose temperature meets their needs. One other important point: as a general rule, endotherms have considerably higher metabolic rates than ectotherms. That’s because they have to burn large quantities of fuel-food-to maintain their internal body temperature.

Detailed explanation-4: -endotherm, so-called warm-blooded animals; that is, those that maintain a constant body temperature independent of the environment. The endotherms primarily include the birds and mammals; however, some fish are also endothermic.
