What ecological benefit do wetlands provide?

Wetlands are vital ecosystems that offer numerous ecological benefits, and one of the most significant is providing habitat for a diverse array of species. These unique environments support a variety of plant and animal life, including fish, amphibians, birds, and invertebrates, which rely on wetlands for breeding, feeding, and shelter. The complex plant life found in wetlands, such as reeds, sedges, and salt marsh grasses, creates a rich and varied habitat that supports both aquatic and terrestrial organisms.

The ability of wetlands to filter pollutants and retain nutrients further adds to their value by promoting biodiversity. Additionally, wetlands often serve as nurseries for fish species, playing a crucial role in sustaining both local and regional fisheries. By providing this essential habitat, wetlands help maintain ecological balance, enhance biodiversity, and contribute to the survival of many species that might otherwise struggle in less diverse environments.

The other options do not accurately represent primary benefits of wetlands. For instance, while wetlands can play a role in temperature moderation, their main ecological function revolves around habitat provision. Increased soil erosion is contrary to the protective role that wetlands typically serve, as they help stabilize shorelines and reduce erosion. Lastly, while wetlands can naturally treat waste by filtering contaminants, their primary role does not focus
