The term for the process of adapting to environmental changes is adaptation. This biological process occurs when organisms undergo physiological or behavioral modifications in response to alterations in their habitat. It allows species to enhance their survival and reproduction rates in fluctuating conditions, ensuring their evolution over time. Adaptation can occur through natural selection, where advantageous traits become more common in a population. Both structural (physical characteristics) and functional (internal processes) adaptations contribute to the success of an organism within its environment. Understanding adaptation is crucial in fields like ecology and conservation biology.
