freshwater ecosystem
River and pond
A freshwater ecosystem is a biological community inhabiting bodies of water with low salt content—lakes, rivers, streams, ponds, and wetlands.
These systems support distinct plant and animal life adapted to non-saline conditions: The river's freshwater ecosystem includes trout, crayfish, and various aquatic insects.
Freshwater ecosystems cover less than one percent of Earth's surface but harbor a disproportionate share of its biodiversity.
