Answer 1

Adaptation is the evolutionary process where an organism becomes better suited to its habitat .

Adaptation is necessary for the survival of living organisms. As the environment changes, the animals that cannot adapt die out. These adaptations are a result of genetic changes.

Answer 2

Answer:

Adaptation is any change in the structure or behavior of a species which helps it to become better fitted to survive and reproduce in its environment.
