2012 AIPMT-PRE 1 question
-
In an area where DDT had been used extensively, the population of birds declined significantly becauseDDT accumulates along the food chain (biomagnification) and reaches high concentrations in fish-eating birds.
It disturbs calcium metabolism in birds, which causes thinning of the egg shell and premature breaking of eggs.
So many of the eggs laid did not hatch and the bird population declined.
