Citing two examples, explain how an animal can alter its surface area to volume ratio to reduce heat loss?
What will be an ideal response?
Answer: Individual organisms can curl their bodies to effectively reduce their surface area to volume ratios. When a python rolls itself into a ball, the exposed surface area is reduced as much as 85%. Groups of organisms can attain similar results by huddling: Colonies of naked mole rats can maintain a constant body temperature by huddling, whereas an individual will experience a significant loss of body heat if the ambient temperature drops.
