Explanation:

Adaptation is made possible as a result of an organism being exposed to different environmental conditions. These exposure makes it adopt different techniques for its survival which eventually results in it being adapted to the condition and is then passed on as traits to its offsprings. They are then able to survive when met with such environmental condition.

When an organism is exposed to the same conditions all the time then there is lack of genetic variation and adaptation may not occur.
