2. Why is biomass lost in faeces?

  • Because the animal has an instinct to excrete, and therefore biomass is often lost in faeces.
  • Because the animal feels guilty of taking energy from the environment and not giving anything in return, therefore it looses some biomass as faeces.
  • Because not all of the biomass an animal eats as energy can be used, therefore the remaining biomass that hasn't been digested is lost in faeces.
  • Because the biomass an animal eats is excessive to what the animal really needs, therefore the biomass that the animal doesn't need is excreted as faeces.
