'This video covers: - The idea that biomass is just the mass of living organisms - Pyramids of biomass show the amount of biomass at each trophic level of a food chain - Why the amount of biomass decreases as you go up the food chain - How to calculate the efficiency of biomass transfer between levels in a food chain Exam board specific info: AQA - Separate/triple science only IGCSE Edexcel - Everything is relevant to your course! But you also need to know about pyramids of number and energy, which are very similar.
