The organisms activity is unaffected when temperatures are low because they can just adjust to it
Explanation:
Different organisms adapt differently to survive and thrive in various atmospheric conditions including extreme weather conditions.
Organisms undergo adaptation of thermoregulation to regulate their body temperature in accordance with the temperature of its surrounding. Accordingly, organisms are classified as endothermic or ectothermic. Thermoregulation process helps the organism to maintain body homeostasis.
Human body maintains a constant body temperature even when the external temperature is too high or too low.
When the temperature is less, heat loss through evaporation is less and hence less energy is consumed.
Various animals undergo adaptations like hibernation or dormancy to conserve their limited energy sources during low temperature periods.
