Physics · Ecological Adaptations and Thermodynamics

With reference to ecological adaptations, consider the following statements: 1. Animals in cold climates tend to have a higher surface area-to-volume ratio to conserve heat. 2. Desert plants have smaller leaves, thick cuticles, or spines to reduce water loss through transpiration. 3. Arctic animals with thick fur are less sensitive to climate change than tropical species. 4. The role of fur in arctic animals is primarily to provide camouflage rather than thermal insulation. How many of the above statements are correct?
