Ornithologists observed decline in the bird population in an area near a lake after the setting of an industrial unit in the same area.

Question 1

Ornithologists observed decline in the bird population in an area near a lake after the setting of an industrial unit in the same area. Explain the cause responsible for the decline observed.

Question 2

DDT must have entered the trophic levels of food chain (biomagnification). It was accumulated in the birds as it can neither be metabolised nor be excreted. High concentration of DDT disturb calcium metabolism in birds which causes thinning of the eggshells and their ***** breaking, ultimately causing decline in bird populations.
