Biomass transfer, Food security and farming

Question 1

Why is all biomass not transferred?

Answer 1

• Not all part of other organisms are eaten (e.g.bone)
• Not everything ingested is absorbed so it is excreted
• Some biomass is used up for movement and keeping warm

Question 2

(DON’T NEED) What is the equation for efficiency of biomass transfer?

Answer 2

efficiency = biomass transferred to the next level/biomass available at the previous level x 100
