Organisms adapt to environmental changes through the process of evolution and natural selection. Those that possess advantageous traits are more likely to survive and reproduce, passing these traits to the next generation. Adaptations may involve behavioral changes, physiological adjustments, or morphological shifts to better suit the organism's environment. Over time, these adaptations can result in the emergence of new species as populations diverge in response to varying environmental conditions. This ongoing process is crucial for the survival and resilience of life in the face of changing ecosystems.
