Freshwater habitat is a body of water which contains very little or no salt. Examples are rivers, streams, springs, and lakes.
Types of Freshwater Habitat:
The freshwater ecosystems are generally classified into two major groups based on their mobility. They are known as lentic and lotic freshwater habitats:
i. Lotic Freshwater Habitat:
These are running waters which flow continuously in a specific direction e.g. rivers, streams, and springs.
ii. Lentic Freshwater Habitat:
These are standing or stagnant waters, i.e., waters which do not flow e.g. lakes, ponds, swamps, dams or bogs.
Characteristics of Freshwater Habitats:
i. Low SalinitySalinity is the dissolved salt content of a body of water called saline water. It is the measure of the number of grams of salts per kilogram of seawater, which is... More: The salinity or salt content of freshwater is very low about 5 parts per thousand i.e. 0.5%.
