Question

acid deposition effects
what is a long-term effect of acid deposition on forest ecosystems?
decline in tree health
increased biodiversity
rapid forest expansion
enhanced photosynthesis

Explanation:

Acid deposition (acid rain/snow) leaches essential nutrients like calcium from soil, damages tree foliage, and weakens trees over time, leading to long-term decline in their health. The other options are incorrect: acid deposition reduces biodiversity, limits forest growth, and impairs photosynthesis rather than enhancing these factors.

Answer:

decline in tree health
