Wetlands a. are important in improving water quality b. include rivers, streams, ponds, and lakes c. are an example of a marine biome d. are found in the intertidal zone

Answer for the above question is option a. Wetlands are important in improving water. Wetland is a land area that is saturated with water. It takes on the characteristics of a distinct ecosystem. Wetlands improve water quality by trapping sediments, filtering out pollutants and absorbing nutrients that would otherwise result in poor water quality for downstream users. They also provide a filter between surface water and shallow groundwater resources.
