Two equal-sized areas of a disused railway yard were restored.
Area A was kept as short grass. In Area B, patches of long grass and shrubs were allowed to develop.
After three years, students used the same sampling method in both areas.
| Area | Number of plant species recorded | Number of animal species recorded |
|---|---|---|
| A | 5 | 7 |
| B | 16 | 24 |
Using the information and the data, explain which area has greater biodiversity.
A disease causes one plant species in each area to decline.
Predict which area is more likely to remain stable. Explain your answer.
