3 reasons Why is wetland are important to ecosystem?

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.
