What typically happens to biodiversity when an invasive species is introduced?

When an invasive species is introduced to an ecosystem, biodiversity tends to decrease as native species are disrupted. Invasive species often thrive in new environments due to the absence of their natural predators and competitors, allowing them to outcompete native species for resources such as food, space, and light. This competition can lead to a decline in populations of native plants and animals, which can ultimately result in local extinctions.

The introduction of invasive species can alter habitat structure and change food web dynamics, further undermining the resilience and diversity of the ecosystem. As native species decline, the overall biodiversity suffers because a rich variety of species is essential for ecosystem stability and function. The loss of biodiversity can impact ecosystem services, such as pollination, pest control, and nutrient cycling, which are critical for maintaining healthy environments.
