Final answer:
The correct order of processes representing the impact of acid rain is acidification of lakes, accumulation of aluminum, decreased osmoregulation, and suffocation.
Step-by-step explanation:
The correct order of processes representing the impact of acid rain is c) Acidification of lakes→Accumulation of aluminum→Decreased osmoregulation→Suffocation.
Acid rain primarily affects bodies of water with low buffering capacity, leading to the acidification of lakes and streams. In areas with low buffering capacity, acid rain releases aluminum from soils into the water, which accumulates in the aquatic environment. The accumulation of aluminum can cause decreased osmoregulation in aquatic organisms, leading to suffocation and harm to sensitive species.
