If a forest receives less sunlight, what is likely to happen?

• A. Photosynthesis will increase
• B. Photosynthesis will decrease
• C. Temperature will rise
• D. More seeds will germinate immediately

Answer: (B)

Plants use sunlight to power photosynthesis, the process that makes the sugars they need to grow. When a forest gets less sunlight, there isn’t as much light energy available, so the rate of photosynthesis drops. With less food being made, plants don’t grow as quickly. That’s why the best answer is that photosynthesis will decrease. The other ideas don’t fit as neatly: shade doesn’t make the temperature rise, and germination isn’t instantly driven by having less light—seeds usually need the right moisture and warmth, and results aren’t immediate.
