How do invasive species affect surface water ecosystems?

Invasive species can significantly alter surface water ecosystems by disrupting food webs. When non-native species are introduced into an ecosystem, they can compete with native species for resources such as food, habitat, or light. This competition can lead to declines in native populations, which are typically well-adapted to their environment. The elimination or reduction of native species can destabilize the food web, which relies on a balance between producers, consumers, and decomposers.

Invasive species may also introduce new predators or diseases, further affecting the native organisms. This disruption can have cascading effects throughout the ecosystem, impacting biodiversity and the health of the water body. Consequently, the stability and functioning of the ecosystem are compromised, leading to potentially severe consequences for both aquatic life and the quality of the water itself.

The correct understanding of the role of invasive species in ecosystems helps in realizing the importance of management and conservation strategies to protect native species and maintain the balance in surface water environments.
