What is Adaptation ?

WALT :  Define Adaptations. 

The process of change by which an organism or species becomes better suited to its environment. Adaptations are Habits that have changed to help animals or creature to Survive in its environment. I think adaptation means a creature or animal has changed its habits to survive in its environment.

For an Example : A Human being really likes Charles junior. But it's really bad for it's health, so that's why the human being trials for a week to, not eat Charles junior and eat healthy food. Which also is called a Adaptation, because the person has been eating Charles junior and then stops eating for a week, and if the trial works it's going to stop eating.
