• Reasons why only 10% of the biomass is passed on;

  • Oragnisms don't consume every part of the organism
  • Parts that they eat might not be absorbed and egested as faeces
  • Nutrients are used to release energy through respiration
• Efficiency = Biomass transferred to next level / biomass that was available at the previous level x 100
