# Climate change is causing global temperatures to rise. Explain how rising temperatures caused by climate change could affect the distribution and survival of a named animal species.

> Pearson Edexcel A-Level Biology A (9BI0) — 3.3 Climate change · Explain · 5 marks

> Global average temperatures have increased by approximately 1.2 °C since pre-industrial times. Scientists predict that many species will be forced to shift their geographic ranges as a result of climate change.

## Mark scheme (5 marks)

1. Names a specific animal species
2. Rising temperatures mean the habitat/environment of the named species becomes less suitable / changes significantly
3. The species may migrate/move to a different geographic area / further towards the poles or to higher altitudes to find suitable conditions
4. Food sources / prey species may also be affected, reducing food availability for the named species
5. If the species cannot adapt or migrate successfully, population numbers will decrease / the species could become extinct
