Animals can be classified according to their mode of thermoregulation. sort the animals below, indicating their likely thermoregulatory strategy. note that poikilotherms are sometimes referred to as heterotherms.

animals: eagle coyote butterfly salamander walrus arcticshrimp freshwatercatfish
categories: homeothermic endotherm, homeothermic ectotherm, poikilothermic ectotherm

Explanation:  Eagles   are endotherm and homoeothermic.

Coyote are endotherms and homoeothermic.

Walrus are Endothermic and homoeothermic.

The above organisms maintain constant internal body temperature irrespective of fluctuations  in surrounding temperature.

Artic shrimp are ectotherms; and homoeothermic. Despite the fact that it has  negligible source of intenal heat, its environmental temperature is relatively stable, therefore it  is both ectotherms and homoeothermic.

Butterfly, freshwater catfish, Salamander are Poikilothermic.  These organism’s body temperature fluctuates with  the immediate  surrounding temperature. They lack internal body temperature.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
