The primary influence of natural selection on ecosystems is the promotion of traits that enhance species survival and reproductive success. This evolutionary process shapes the physical and behavioral characteristics of organisms, ultimately affecting their interactions within ecosystems. As species adapt to their environments, they establish complex relationships, influencing community dynamics and ecosystem function. Natural selection also drives biodiversity by favoring variations among populations. Understanding this influence is crucial for conservation strategies aimed at preserving genetic diversity and ecosystem resilience in the face of environmental challenges.
