Answer:
Step-by-step explanation:
Homeostatic means maintaining a stable internal and external heat. Since both needs to be kept at balance, it is necessary animals either gain or lose heat in their day to day activities.
Heat is lost or gained by various methods such as
Conduction: Loss/Gain of heat by bodies in contact
2. Radiation: Lost/Gain of heat by bodies not a contact
3. Radiation: Loss/Gain of heat due to Air current
So a. Kangaroos licking their arms to keep cool, is doing it through Evaporative cooling
A snake lying in the sunlight to warm up is by Radiation
Elephants flapping their ears to dissipate heat is by Convection
A snake lying on a warm rock to warm up is by Conduction
