Detailed explanation-1: -Organisms living in the desert have to conserve water for their survival. They have thick skin, long legs with flat and cushioned soles that protect them from the hot sand and prevents the loss of water from the body.

Detailed explanation-2: -Some desert plants store water in their leaves, stems, or roots. Others have thick, waxy skin that helps prevent water loss. Some desert plants have small leaves that help reduce evaporation. Others have deep taproots that help them reach the underground water sources.

Detailed explanation-3: -Some animals have developed salt glands, a physical adaptation that allows the secretion of salt without the loss of water. The absence of sweat glands, and the concentration of urine are other physical adaptations made by desert animals.

Detailed explanation-4: -Hence, desert animals have a thick skin to prevent loss of water from the body Their legs are long with flat and cushioned soles. The nostrils are protected by folds of skin The eyelashes are long and thick. Rats, snakes, spiders, lizards in deserts live in deep burrows during daytime and are active at night.

Detailed explanation-5: -The roots of desert plants are also adapted to help them survive. Some plants have shallow, widespread roots to absorb a maximum of rainfall moisture. Others have deep taproots to get water that is deep underground.
