Scientists investigated whether a waste storage area was causing pollution. They measured the concentration of toxic chemicals in the soil and counted the plant species at different distances from the storage area.
| Distance from the waste storage area in m | Concentration of toxic chemicals in the soil in mg/kg | Number of plant species in 1 m² |
|---|---|---|
| 5 | 84 | 3 |
| 20 | 46 | 7 |
| 50 | 18 | 12 |
| 100 | 4 | 16 |
Explain how the results support the conclusion that the waste storage area is causing land pollution and reducing biodiversity.
