Which of the following is a potential impact of AIS on native ecosystems?

• A. Increased biodiversity
• B. Disruption of food chains and habitat loss
• C. Enhanced native fish populations
• D. Improved water clarity

Answer: (B)

Disruption of food chains and habitat loss as a potential impact of Aquatic Invasive Species (AIS) on native ecosystems is accurate because these non-native species often compete with native organisms for resources such as food, light, and space. This competition can lead to a decline in native species, which upsets the established food chains within the ecosystem. Additionally, AIS can alter habitats—such as by changing the physical environment (like vegetation structure) or chemistry of the water—leading to further loss of native species and the services they provide. When AIS thrive in an environment, they can also introduce new diseases or parasites that further threaten local populations. This cascading effect disrupts the balance of the ecosystem, reducing biodiversity and impacting species interactions. Therefore, the significant threat posed by AIS to food chains and habitats highlights the importance of monitoring and managing these species to protect native ecosystems.
