CAIE IGCSE Biology 19.2.12 Pyramids of biomass
Practise explaining why biomass can represent feeding relationships more usefully than organism counts in food chains.
How this is tested
- explain why one large organism and one tiny organism distort a pyramid of numbers
- link biomass to the amount of food or energy available at each trophic level
