Both running water and stagnant water can be found in freshwater ecosystems, which include a variety of habitats such as rivers, streams, lakes, ponds, wetlands, and swamps. Specifically:

• Running water is characteristic of lotic ecosystems, which include flowing water bodies like rivers and streams.
• Stagnant water is typical of lentic ecosystems, which include standing water bodies such as lakes, ponds, and pools. Additionally, wetlands and swamps often contain stagnant or slowly moving water, with water levels that may fluctuate due to rain and flooding.

Thus, freshwater ecosystems encompass both running and stagnant water environments in close proximity or within the same general area

. Examples include:

• Rivers and streams (running water)
• Lakes and ponds (stagnant water)
• Wetlands and swamps (which may have stagnant or slow-moving water)

These ecosystems support diverse aquatic and amphibious life adapted to either flowing or still water conditions

. In summary, you can find both running and stagnant water within freshwater ecosystems such as river basins that include streams, lakes, and wetlands
