What is one impact of invasive species on native aquatic ecosystems?

Invasive species can significantly disrupt native food webs and outcompete local species for resources. When a non-native species is introduced to an aquatic ecosystem, it often lacks the natural predators or controls that would normally keep its population in check, allowing it to thrive and spread rapidly. This unchecked growth can lead to a decline in native species that struggle to compete for food, habitat, and other resources.

As invasive species proliferate, they can alter the availability of essential resources in the ecosystem, which can disrupt the relationships among various organisms. For example, if an invasive fish species dominates a habitat, it may reduce the population of native fish by consuming their food sources or predating on them directly. This imbalance can lead to a reduction in overall biodiversity, harming the ecological integrity of the ecosystem.

In contrast, the other options do not accurately reflect the effects of invasive species. They do not enhance biodiversity or natural resources, and the idea that invasives can adapt without issue overlooks the tangible harm they can cause to native populations and habitat stability.
