The term used to describe the capacity of an organism to survive in changing conditions is called adaptability. This ability enables species to adjust to various environmental changes, such as climate fluctuations, habitat alterations, or shifts in food availability. Adaptability can manifest through evolutionary processes, where genetic variations that confer survival advantages are naturally selected over generations. It is essential for species survival, resilience, and is a crucial aspect of natural selection. Organisms with higher adaptability are more likely to thrive in fluctuating environments and may evolve new traits over time.
