Polar Ecosystems Compared
Compare Arctic and Antarctic ecosystems — the Arctic has both terrestrial (tundra) and marine ecosystems supporting large land mammals and indigenous human communities, while the Antarctic is almost entirely marine-based with virtually no land plants or mammals; both regions have short, intense food chains anchored by phytoplankton and krill, and both are disproportionately affected by climate change and human activity
Suggested ages 9–11
Evidence of understanding
- Compare Arctic (terrestrial + marine, land mammals, human communities) with Antarctic (almost entirely marine, no land mammals)
- Explain that both polar food chains depend on phytoplankton and krill at the base
- Describe why polar ecosystems are particularly vulnerable to climate change (short food chains, specialised organisms)
Assessment prompt
Can Polar Ecosystems Compared compare the Arctic and Antarctic ecosystems — explaining that the Arctic has land animals and people while Antarctica's life is almost all in the sea, and that both depend on tiny creatures like krill?
