What does natural selection contribute to in ecosystems?

Natural selection is a fundamental mechanism of evolution that contributes significantly to the evolution of species and, consequently, to biodiversity within ecosystems. It operates on the principle that individuals with traits favorable for survival and reproduction in a particular environment are more likely to pass those traits on to the next generation. Over time, this process leads to adaptations that can result in the emergence of new species and an increase in the variety of life forms in a given ecosystem.

As species adapt to their environments through natural selection, they can exploit different ecological niches, which enhances biodiversity. This diversity is crucial for ecosystem resilience, allowing communities to withstand environmental changes and maintain functional stability. Therefore, natural selection is a driving force behind the dynamic changes in species composition and richness, ultimately enriching the ecological tapestry of life on Earth.
