What is adaptation give examples?

Adaptation refers to the process by which organisms adjust to their environment to enhance survival and reproduction. This can occur through physical changes, such as the thick fur of arctic foxes for insulation in cold climates, or behavioral changes, like migratory patterns in birds seeking warmer regions during winter. Another example is the development of antibiotic resistance in bacteria, allowing them to survive in the presence of antibiotics. Adaptations can be structural, physiological, or behavioral, depending on the specific challenges posed by the environment.
