Pennsylvania Pesticide Category 23 Practice Test

The potential impact of invasive species on local ecosystems is that they may disrupt the balance of native species. Invasive species often outcompete native species for resources such as food, water, and habitat. This competition can lead to a decline in native populations, altering community structures and reducing biodiversity. When invasive species thrive in their new environments, they can change vital ecosystem processes, such as nutrient cycling and natural succession, which can have cascading effects throughout the ecosystem.

In contrast, options such as enhancing biodiversity, providing food for local wildlife, or improving soil quality generally do not apply to invasive species. While some invasive species may have certain beneficial aspects, their overall impact tends to be negative, primarily due to the disruption they cause to existing relationships within the ecosystem.
