What role do wetlands play in Nebraska's ecosystems?

Wetlands play a crucial role in Nebraska's ecosystems by purifying water and providing diverse habitats. They act as natural filters, trapping sediments and pollutants from surface runoff, which helps to improve water quality in nearby rivers and lakes. This filtration process is essential in maintaining the health of aquatic ecosystems and supporting a wide range of wildlife.

Additionally, wetlands are rich in biodiversity, offering habitat to various species, including birds, amphibians, insects, and plants that are specially adapted to these environments. This diversity is vital not only for the species that inhabit wetlands but also for the overall ecological balance within Nebraska's landscape. By providing breeding grounds and shelter, wetlands support both terrestrial and aquatic life forms, contributing significantly to the state's ecological health.

The other options do not encompass the comprehensive benefits that wetlands provide. They are not primarily barriers against wildfires, while they may indirectly support agriculture, that is not their main role. Furthermore, wetlands support a range of wildlife, not just aquatic species, reflecting their importance in both aquatic and terrestrial ecosystems.
