Question

Acid rain is produced when rain mixes with chemicals such as sulfur dioxide in the air. This may result in

• A. Lowering the pH in ponds, thus limiting the survival of many organisms
• B. Lowering the pH in ponds, thus affecting water temperature
• C. Raising the pH in ponds, thus encouraging the growth of organisms
• D. Raising the pH in ponds, thus limiting animal development
• E. Depleting atmospheric carbon dioxide available for photosynthesis

Answer 1

Answer: (A)

Lowering the pH in ponds, thus limiting the survival of many organisms

Acid rain will lower down the pH of pond water and will cause an adverse effect on survival of many organisms as the acidic environment does not support the growth and existence of organisms.

Normal pond water has neutral or slightly alkaline pH; acid rain would lower down its pH.

Water temperature of the pond is determined by the availability of Sunlight and depth of water.

pH does not affect the level of available dissolved carbon dioxide.

Therefore, the correct answer is option A.
