CAIE IGCSE Biology 19.2.6 Consumers may be classed as primary
Practise assigning primary, secondary and tertiary consumers in food chains and webs, including organisms feeding at more than one level.
How this is tested
- identify consumer level from a chain, web or labelled trophic-level diagram
- recognise species that feed as both secondary and tertiary consumers in a food web
- predict a population change when one consumer level increases in a chain
