Life in Hot Deserts

The video explores the harsh conditions of desert environments, which cover a third of Earth's land and receive minimal precipitation. It highlights the physical and behavioral adaptations of organisms like camels and fennec foxes that enable them to survive extreme temperatures. Camels use their fur and humps for temperature regulation and energy storage, while fennec foxes have large ears for cooling. Behavioral adaptations, such as being crepuscular or nocturnal, help animals avoid the intense heat. These adaptations are crucial for survival in the unforgiving desert.
