IB ESS 2.3.6 Ecosystems as carbon stores/sinks/sources
Practise judging when ecosystems act as carbon stores, sinks or sources and linking land-use change to atmospheric and ocean impacts.
How this is tested
- explain how deforestation shifts a forest from carbon sink to source
- link taiga deforestation to higher greenhouse gases and ocean change
- compare human impacts on carbon and nitrogen cycles through combustion and agriculture
