Question

Q52. For Biomagnification to occur, the pollutant must be
1.  Short-lived                    2. Immobile
3.  Soluble in water                        4. Biologically active
Select the correct answer using the codes given:
  1. (a) Only 2 and 4
  2. (b) Only 2, 3 and 4
  3. (d) All of the above
  4. (c) Only 4


Solution

The correct option is D (c) Only 4
If a pollutant is short-lived, it will be broken down before it can become dangerous. If it is not mobile, it will stay in one place and is unlikely to be taken up by organisms. If the pollutant is soluble in water, it will be excreted by the organism. Pollutants that dissolve in fats, however, may be retained for a long time.
