Desert lizards bask in the sun and absorb heat, when their body temperature drops below the comfort zone, but move into shade, when the ambient temperature starts increasing. This is an example of -------------adaptations.

Desert lizards manage to keep their body temperature fairly constant by behavioural means. They lack the physiological ability that mammals have to deal with the high temperatures of their habitat.

They bask in the sun and absorb heat when their body temperature drops below the comfort zone, but move into the shade when the ambient temperature starts increasing. Some species are capable of burrowing into the soil to hide and escape from the above-ground heat. These actions are examples of behavioural adaptations.
