CAIE IGCSE Biology EXTENDED 19.2.16 Pyramids of energy
Practise judging why pyramids of energy give a clearer food-chain model than number or biomass pyramids when comparing trophic levels.
How this is tested
- compare energy, biomass and number pyramids to decide which best represents a food chain
- explain why energy pyramids avoid misleading shapes caused by organism size or numbers
