Define phenotypic adaptation. Give one example.

(N/A) Phenotypic adaptation refers to the physiological,morphological,or behavioral changes that occur in an organism's phenotype in response to environmental pressures or stressors. These adjustments help the organism survive and reproduce in its specific habitat.
Example: Desert plants,such as $Opuntia$,possess thick cuticles and sunken stomata on their leaf surfaces to minimize water loss through transpiration.
