DDT residues are rapidly passed through food chain causing biomagnification because DDT is :

A

water soluble

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
DDT is a chlorine containing pesticide used in agriculture. DDt is rapidly passed through food chain causing biomagnification because it is stable, accumulates in the soil and concentrates in the fatty tissue or internal organs of body (as DDT is fat soluble substance). So, DDT takes may years to break down and it enters into body of other organisms with predation. So the amount of DDT biomagnifies.
