Why are birds that inhabit areas with high acid deposition more likely to lay eggs with thin shells?
A)acid deposition increases the effects of DDT which has already been implicated in thinning eggshells.
B)high rates of cancer due to acid deposition impact birds' ability to form eggs.
C)acid deposition acts as an endocrine disruptor that interferes with reproductive hormones in bird species.
D)in acidic soils calcium, an important nutrient for eggshell production, washes away and so less is available to birds in their diets

Question

Acid deposition leads to the leaching of calcium from the soil, which in turn reduces the availability of this crucial nutrient for birds. Calcium is essential for the formation of strong eggshells, and its scarcity results in the production of eggs with thinner shells.
