The presenter explains how processes carried out by living organisms can affect the amounts of biomass and energy transferred from one trophic level to another in a food chain. The presenter uses examples of simple food chains and pyramids of biomass to show the relative amounts of biomass at each trophic level. The video also discusses the efficiency of energy and biomass transfers between trophic levels and the reasons why energy and biomass transfers are often inefficient. Finally, the presenter explains how decreasing the number of trophic levels can increase the efficiency of the food chain and support more organisms in the highest trophic level.\n
