A fish species can survive only where the long-term average water temperature is between 15.0 °C and 18.0 °C.
The table shows current average water temperatures and temperatures predicted after global climate change.
| Depth below sea surface in m | Current average water temperature in °C | Predicted average water temperature in °C |
|---|---|---|
| 10 | 17.5 | 19.5 |
| 30 | 16.5 | 18.5 |
| 50 | 14.5 | 16.5 |
| 70 | 13.5 | 15.5 |
Explain the likely change in the depth distribution of the fish species if the predicted temperatures occur.
