GCSE Biology - Pyramids of Biomass #87

The video tutorial explains the concept of biomass in a food chain, highlighting how biomass decreases as you move up trophic levels due to energy loss. It details the reasons why only about 10% of biomass is transferred between levels, such as incomplete consumption, non-absorption, and energy use in respiration. The tutorial also covers how to calculate the efficiency of biomass transfer using specific examples.
