  1. Reduced crop yields

  2. Increased forest fires

  3. Enhanced plant growth

  4. Damage to tree seedlings
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ozone depletion can have several negative impacts on terrestrial ecosystems, including reduced crop yields, increased forest fires, and damage to tree seedlings. Enhanced plant growth is not a known impact of ozone depletion.
