How do desert animals cope with high daytime temperatures and lack of water?
- Animals have different physiological and behavioural adaptation to environmental stresses;
The kangaroo rat in north american deserts is capable of meeting all its water requirements by internal oxidation of its body fat
They can concentrate its urine so that the minimum volume of water is used to expel excretory products.
They absorb heat from sun when body temperature falls below the comfort zone and moves to shade when temperature starts increasing.
Some species burrow into the soil to escape from above ground heat.
In this way organisms cope with day temperature and lack of water.
