The desert is hot and dry, while the tundra is cold and frozen. In a desert climate, anatomical structures and behaviors that protect an organism from heat are useful adaptations. Most organisms have adaptations that help them conserve water, because water can be scarce in desert climates. For example, many organisms in the desert are nocturnal, which means they’re most active at night when temperatures are cooler.
because in biosphere when hydrosphere is disturbed means animals and plants in biosphere sometime Will miss water or watering will fails but also in atmosphere some factors like humidity and vapour will change
