  • Plants: 
    • Xerophytes: adapted to dry conditions (e.g. cacti with spines to reduce water loss, deep tap roots to access underground water). 
    • Succulents: store water in stems or leaves.
    • Waxy coatings reduce water loss.
  • Animals: 
    • Nocturnal behaviour to avoid heat. 
    • Camels store fat in humps and can go without water for extended periods. 
    • Kangaroo rats get moisture from seeds and live in burrows to escape heat.
