Answer» Adaptation is the quality of the organism (morphological, physiological, behavioural) that enables the organism to survive and reproduce in its habitat. It adapts organisms to live in different types of habitats. Adaptation of plant and animal in desert: Adaptations of desert plants are as follows: i. Desert plants have cuticles to minimise transpiration. ii. In some desert plants, leaves are modified into spines to minimise loss of water. iii. They have long roots and adaptations to reduce transpiration, e.g., Acacia. Adaptations of desert animals are as follows: i. Desert animals have concentrated their urine for minimum loss of water, e.g., Kangaroo rat. ii. Desert animals absorb heat from the sun, when the body temperature drops below the comfort zone. iii. They live in burrows during hot season and have little water requirement, e.g., camel. |
