Homework Help - Freshwater Plants & Vegetation: Freshwater ecosystems 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; light and oxygen are 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.
