What can be a consequence of invasive aquatic species in local ecosystems?

• A. They help maintain balance in the ecosystem
• B. They can outcompete native species
• C. They lead to increased biodiversity
• D. They decrease pest populations

Answer: (B)

Invasive aquatic species are known for their ability to disrupt local ecosystems, primarily through competition with native species. When these invasive species enter a new habitat, they often possess growth rates or reproductive advantages that allow them to thrive in conditions where native species may struggle. This can lead to them outcompeting the native species for vital resources such as food, mating opportunities, and habitat space. As a result, the populations of native species may decline, potentially leading to local extinctions and a reduction in overall biodiversity. The ecological balance critical to the health of the ecosystem may also be destabilized, illustrating the profound impact invasive species can have. Their introduction can lead to cascading effects throughout the food web, influencing not just the directly competing organisms, but also those that rely on native species for food, shelter, or other ecological functions. Thus, the outcompeting of native species is a significant consequence of the introduction of invasive aquatic species.
