It may be divided into two categories: the lentic or still water ecosystem and the iotic or the flowing water ecosystem. However, as the air temperature drops with the arrival of winter, the water that is closest to the surface may drop below the temperature of the water at the bottom of the lake, causing it to sink and the warmer bottom water to rise. A lack of freshwater access can be a cause of conflict between communities. Freshwater Ecosystems. The ecosystems in rivers and streams, for example, bring salts and nutrients from the mountains to lakes, ponds, and wetlands at lower elevations, and eventually they bring those nutrients to the ocean.
