An invasive species is best described as a non-native species that spreads rapidly and can disrupt local ecosystems. These species often thrive in new environments due to a lack of natural predators or competitors that help to maintain balance in the ecosystem. Their rapid spread can lead to significant changes in habitat, which may negatively affect native species by outcompeting them for resources such as food and space, or even causing declines in their populations. This disruption can have cascading effects throughout the ecosystem, leading to reduced biodiversity and altered ecological functions. Understanding the impact of invasive species is crucial for managing and protecting local ecosystems.

Other options illustrate different concepts. The description of a native species that thrives in its environment focuses on species that are integral to their native ecosystems. A species that provides benefits to native wildlife is typically advantageous and supports biodiversity, while a species that has no impact on the ecosystem does not play a significant role, making it less relevant in the context of biodiversity and ecosystem health.
