What are potential impacts of invasive species in Maine's water bodies?

The correct answer highlights a significant concern regarding invasive species in Maine's water bodies. Invasive species can dramatically alter the existing ecosystems by outcompeting native species for resources such as food, space, and sunlight. This disruption can lead to declines in native populations, thereby reducing biodiversity. Additionally, invasive species can change the physical and chemical attributes of the habitat, which can further impact native organisms and the overall health of the ecosystem.

The presence of invasive species can lead to a loss of habitat for fish and other wildlife that rely on native flora and fauna for survival. As the invaders establish themselves, they can alter food webs, affect nutrient cycling, and create imbalances that can be difficult to reverse.

In contrast, the other choices suggest outcomes that do not align with the established understanding of the effects of invasive species. Improved water quality is unlikely because invasive species can lead to nutrient imbalances and poor ecological health. Increased biodiversity is not accurate, as invasive species tend to decrease it by displacing native species rather than adding to it. Finally, a decrease in fishing regulations is unrelated to the ecological impacts of invasives and would not be seen as a direct consequence of their presence. This highlights the importance of recognizing the negative implications that invasive species can have on
