The major characteristic of a fresh water habitat is the possession of…

A. high turbidity

B. high density

C. low salinity

D. high current

QUICK ANSWER…

C

DETAILS…  

Fresh water habitat is characterized by low salt content as against saltwater habitat.

Now for the right answer to the above question:

  1. Turbidity has to do with the ability of solute particles in water to scatter light incident on it. It is a measure of clarity of water. There are fresh waters that are very clean with low turbidity. so, A is quite incorrect.
  2. Salt water is generally denser than fresh water, this is due to the dissolved salt content. Fresh water has lower density when compared to salt water. So, B is also incorrect.
  3. Fresh water has very low quantity of dissolved salt. So, C is correct.
  4. D is incorrect; high current has nothing to do with whether the water is salt or fresh, it has to do with the pressure gradient of the landscape, or the speed of the water flow.

QUICK ADVICE…

You may please note that:

  • What differentiates fresh water from salt water is mainly the quantity of dissolved salt in both.
