A wetland is a biome which has both water and land that are intermixed in various ways. According to the type of the wetland, the ecosystem differs.

Bogs: Wetland with water from precipitation and no inflow or outflow of surface or ground water.  

Soil: Acidic, infertile with less nutrient content

Vegetation: Acid-loving plants

Swamps: Forest wetlands near rivers and lakes.

Soil: well draining, mineral soil

Vegetation: Trees and bushes. Swamps are classified according to the vegetation, like coniferous swamp, hardwood swamp, shrub swamp etc

Marsh: Wetlands mostly inundated with water leading to waterlogged soil  

Soil: Organic and mineral soil

Vegetation: Hydrophytic plants adapted to waterlogged soil

Estuaries: Wetland regions enclosed by land one side where fresh water mixes with saline ocean water.  

Soil: Saline alkaline soil

Vegetation: Mangrove trees

Rivers and lakes are water bodies that form a part of wetlands.  

Rivers are flowing water bodies which flows through water current and picks up sediments as it flows.

Lakes are stationary water bodies that are enclosed by land mass on all its sides.

The wetlands act as a natural filter and receive all the sediments, pollutants etc which are dissolved in water and carried by the rivers and other water sources.
