Discuss any five adaptive traits that enable camels to survive in arid environmental conditions
Explain why these ecological and physiological trait(s) are vital to the survival and persistence of the animal population. Put emphasis on the importance of adaptation to the environment and the development of these traits.

2) describe at least one distinct ecological condition(s) affecting the species/population (e.g. habitat type where they are found; food resource or prey item; etc.)
3. explain why these ecological and physiological trait(s) are vital to the survival and persistence of the animal population. Put emphasis on the importance of adaptation to the environment and the development of these traits.
