CAIE IGCSE Biology 20.2.1 Biodiversity as the number
Practise defining biodiversity and using forest, ecosystem or species data to decide how area changes affect species variety.
How this is tested
- distinguish biodiversity from population, community and ecosystem in definition questions
- use forest-area tables or percentage data to calculate loss and infer biodiversity change
- predict how clearing forests for monocultures changes the variety of species in an area
