Special modification which enable an organism to survive in its habitat is known as adaptation. Adaptation is a biological process in which an organism undergoes certain physical or behavioral changes that make it better suited to survive and reproduce in its environment. These modifications can be structural, physiological or behavioral and may occur over long periods of time through natural selection or quickly through genetic mutations. Adaptation helps organisms to cope with changes in their environment, increases their chances of survival, and enables them to exploit available resources for their own benefit.
