Answer:
C
Explanation:
When it precipitates, the acid in the soil becomes dissolved forming an acidic solution. The low pH solution dissolves the calcium ions in the soil washing them away in runoffs and also leaching them deeper into the soil. This depletes the calcium ions hence making them unavailable to the birds. Calcium intake is important in birds because the ion is a significant component of eggs shells (makes them strong and not brittle hence the eggs don’t break easily)..
1) Carbon is removed from the air by photosynthesis in plants
2) Feeding, from animals, passes carbon along food chain/web
3) Carbon dioxide is released back into the air by:
-animals & plants respiring
-bacteria/fungi acting as decomposers
-Burning of fossil fuels (combustion)
