The introduction of an invasive species is a significant factor that can disrupt an ecosystem and lead to biodiversity loss. Invasive species are non-native organisms that, when introduced to a new environment, can outcompete native species for resources like food, habitat, and water. They often have no natural predators in their new environment, allowing them to proliferate quickly and dominate ecosystems.

As these invasive species thrive, they can alter habitats and disrupt food webs, leading to a decline in native species populations. This can result in a loss of biodiversity, as diverse ecosystems rely on a variety of species to maintain balance and resilience. The negative impacts on both individual species and ecosystem functions illustrate how the introduction of invasive species can severely affect biodiversity.

In contrast, stable climate conditions and effective pollution control tend to promote biodiversity by creating a predictable environment in which native species can thrive. The absence of competitive species can also provide opportunities for certain species to flourish, but it generally wouldn’t have the same disruptive effect as introducing a problematic invasive species.
