Adaptations in Kangaroo rat : The Kangaroo rat in North America deserts is capable of meeting all its water requirement by internal oxidation of its body . It can also concentrate its ** so that minimal volume of water is used to expel excretory products.
Adaptation in Desert plants: Many desert plants have a thick cuticle on their leaf surface and have their stomata arranged in deep pits to minimise water loss through transpiration. They also have a special photosynthetic pathway known as Crassulacean Acid Metabolism (CAM) that enables their stomata to remain closed during day time so as to minimise transpiration.
Some desert plants like Opuntia have no leaves. Their leaves are reduced to spines and photosynthesis occurs in flattened stems.
