Homework Help - Freshwater Biomes & Ecosystems: Freshwater biomes include lakes, rivers, ponds, and streams; they all have low salt concentration. Ponds and lakes can vary in size and have limited plant and animal species. Rivers and streams originate in headwaters; you can see different specie as you move from the headwaters to the mouth of the river with light and oxygen being the determining factors. Wetlands are standing water like marshes and swamps; they have a large variety of plant and specie, including reptiles, amphibians, and birds. Some, like salt marshes, have a higher concentration of salt so they are not considered freshwater biomes.
