Any quality of an organism that allows it to live and reproduce in its own place is called adaptation. It is a fixed attribute and living things tend to adapt to their environment. Desert plants with a thick cuticle or submerged stomata to reduce water loss by changing the air are an example of adaptability. Organisms also show physical adaptations such as people exhibiting high altitude illnesses such as nausea, vomiting, heart palpitations, etc. and they become accustomed to the environment after some time.
