⭕ B. Increased vegetation
⭕ A. Depletion of ozone
⭕ C. No effect on vegetation
⭕ D. Depletion of vegetation
📚 Explanation:
The greenhouse effect leads to an increase in global temperature by trapping heat in the Earth's atmosphere.
🔹 A moderate rise in temperature and CO₂ levels can enhance photosynthesis and thus promote increased vegetation in some regions.
Extreme warming, however, may negatively impact ecosystems — but in the context of the question, **vegetation increase** is the expected answer.
The greenhouse effect leads to an increase in global temperature by trapping heat in the Earth's atmosphere.
🔹 A moderate rise in temperature and CO₂ levels can enhance photosynthesis and thus promote increased vegetation in some regions.
✔ Hence, one significant effect is increased vegetation.
Extreme warming, however, may negatively impact ecosystems — but in the context of the question, **vegetation increase** is the expected answer.
👉 Therefore, the correct answer is: B. Increased vegetation
Key Points on Greenhouse Effect:
- Greenhouse gases: CO₂, methane, water vapor.
- Effect: Traps heat, increases global temperature.
- Vegetation: May increase due to enhanced photosynthesis.
- Concerns: Excessive warming may cause climate imbalance.
