On a wetland nature reserve, bees pollinate the flowers of one species of marsh plant, and bank voles eat the fruits of this plant. Scientists recorded the number of bee visits to flowers and the number of marsh plants bearing fruit in two patches of the reserve.
| Patch | Measurement | Early survey | Later survey |
|---|---|---|---|
| North | Bee visits per 100 flowers per hour | 24 | 8 |
| North | Plants bearing fruit per 100 plants | 72 | 31 |
| South | Bee visits per 100 flowers per hour | 18 | 17 |
| South | Plants bearing fruit per 100 plants | 61 | 59 |
Use the data to explain how a continued fall in bee visits in the North patch could affect the bank vole population. Compare the two patches in your answer.
