Question

How do plants and animals adapt to water scarcity?OR Explain briefly the ‘rivet popper hypothesis’ by Paul Ehrlich.

Answer 1

Explanation:

Plants found in deserts are well adapted to cope with harsh desert conditions such as water scarcity and scorching heat. Plants have an extensive root system to tap underground water. They bear thick cuticles and sunken stomata on the surface of their leaves to reduce transpiration.

The two main adaptations that desert animals must make are how to deal with lack of water and how to deal with extremes in temperature. Many desert animals avoid the heat of the desert by simply staying out of it as much as possible. ... The kidneys of desert animals concentrate urine, so that they excrete less water.
