IB Biology D4.3.4 Polar habitat changes
Practise reading polar ecosystem evidence on sea ice, species ranges and penguin colonies, then linking warming to habitat and population change.
How this is tested
- distinguish Arctic and Antarctic sea-ice trends using data, not general assumptions
- interpret penguin colony changes in relation to local sea-ice season patterns
- outline how warming alters polar habitats, pest species and predator ranges
