Question 6 • Earth and Space Science

If large amounts of synthetic fertilizer disrupted the nitrogen cycle, what would most likely happen to plant growth over time?

Answer
A
It would improve at first, then possibly decrease due to imbalance.
B
It would stop immediately because plants need carbon dioxide instead.
C
It would increase quickly and stay high.
D
It would be unaffected because nitrogen is always available.

Explanation

Nitrogen is an essential nutrient that plants use to grow, so added synthetic fertilizer may initially increase plant growth. But excessive fertilizer can disrupt the nitrogen cycle and create nutrient imbalances or harm soil and water ecosystems. Over time, those effects could reduce plant growth, making “improve at first, then possibly decrease due to imbalance” the best answer.
