What effect do invasive plant species often have on native forests?

• A. They improve habitat quality for local fauna
• B. They often outcompete native species
• C. They lead to more diverse ecosystems
• D. They have no significant impact

Answer: (B)

Invasive plant species frequently outcompete native species for resources such as sunlight, water, and nutrients. This competitive advantage can lead to significant alterations in the structure and composition of local ecosystems. Native plants, which have evolved over time in their specific environments, may not have developed the same adaptations that would enable them to thrive alongside invasive species that often grow more rapidly or have fewer natural predators. As a result, the introduction of invasive plants can result in a decline of native flora, which subsequently affects the fauna that depends on these native species for food and habitat. The overall effect is a reduction in biodiversity and an imbalance in the ecosystem, as the invaders establish dominance over the area and disrupt established ecological relationships.
