Stay in & Puzzle | Freshwater Ecosystem
Rivers, creeks, lakes, ponds, and streams are all freshwater habitats. So are wetlands like swamps, which have woody plants and trees; and marshes, which have no trees but lots of grasses and reeds. Wetlands connect land and water, serving as natural filters, reducing pollution, controlling floods, and acting as nurseries for many aquatic species. Rivers, lakes, and estuaries serve as important transportation, recreation, and wildlife hubs.
A recent study by an international research team used satellite photos and computerized mapping technologies to inventory all of the lakes on Earth. The team found about 117 million lakes, covering almost four percent of the world’s land surface, not counting the glaciers on Greenland and Antarctica.
