Freshwater biomes are defined as having low concentration of salt usually less than 1%. The freshwater biome accounts for one fifth of the area of the earth and supplies half of our drinking water. Freshwater normally begins as snow melt on mountain tops in the spring that eventually drains into mountain streams, rivers, ponds, and lakes. In shallow rivers, green algae and plants grow from the banks, which feed insects, and snails that get eaten by fish, salamanders, turtles and frogs. Plankton is not a part of the river ecosystems because of the way the water moves.
You will find still water in ponds and lakes. Ponds are shallow and support the life of many plants as producers. Deep lakes depend a lot on phytoplankton. In ponds and lakes there are many different insects, shellfish, snakes, fish, and land animals that depend on them for food.
