What is a freshwater wetland pond lake ocean or marsh?

The term wetlands encompasses a wide variety of aquatic habitats including swamps, marshes, prairie potholes, flood plains, and fen.

Natural wetlands are lands which, due to geological or ecological factors, have a natural supply of water-either from tidal flows, flooding rivers, connections with groundwater, or because they are perched above aquifers or potholes. Wetlands are covered or soaked for

at least a part, and often all, of the year. This makes wetlands intermediaries between terrestrial and aquatic ecosystems. They are neither one or the other, and yet they are both.
