The photograph below shows a forest that has been affected by acid rain.

Question

How has the chemical change in precipitation affected the stability of this ecosystem?

a
The forest has become more stable because its terrain has become secured by grass and shrubs.
b
The forest has maintained the same level of stability because its terrain remains fully protected from erosion.
c
The forest has become more unstable because its terrain has become more likely to be eroded.
d
The forest has become alternately stable and unstable from falling trees and rocks.

Answer 1

c
The forest has become more unstable because its terrain has become more likely to be eroded. Acid rain can weaken the soil and make it more susceptible to erosion, which can lead to instability in the ecosystem.
