Question

Some insects, such as bees, have a variable body temperature but do not use shivering thermogenesis. They are known as.

a) Endothermic
b) Poikilothermic
c) Ectothermic
d) Homeothermic

Answer 1

Bees are considered poikilothermic animals because their internal body temperatures vary with the environment, and they do not use shivering thermogenesis to regulate their body temperature.

Step-by-step explanation:

Insects such as bees, which have a variable body temperature that does not remain constant in the face of differing environmental temperatures and do not use shivering thermogenesis, are known as poikilothermic animals.

Poikilotherms have internal temperatures that vary along with the environment.

In contrast, endotherms are capable of maintaining a mostly constant internal body temperature regardless of environmental conditions through metabolic heat production. Bees are thus categorized as poikilotherms as their internal temperature can change, but they do not fit entirely within the traditional definition of ectotherms, who primarily rely on the external environment to regulate their body temperature.
