What is a common consequence of invasive species on native environments?

• A. They often improve habitat diversity.
• B. They can lead to the extinction of native species.
• C. They help native species to thrive.
• D. They increase food availability for native wildlife.

Answer: (B)

Invasive species are non-native organisms that, when introduced to a new environment, can disrupt the existing balance of that ecosystem. One of the most significant consequences of invasive species is their potential to lead to the extinction of native species. This occurs through various mechanisms such as competition for resources, predation, and the introduction of diseases to which native species have no immunity. As invasive species often thrive in their new environments due to a lack of natural predators and competitors, they can outcompete native species for food, space, and other resources essential for survival. This competitive advantage can diminish the population of native species, making them more vulnerable to decline and, in some cases, extinction. Therefore, the impact of invasive species on biodiversity is profound, as they can fundamentally alter community structures and lead to the loss of native species, thereby reducing biodiversity. This issue underscores the importance of monitoring and controlling invasive species to protect native habitats and species.
