Energy losses

Animals like zebras take in a large amount of plant biomass and convert it into a small amount of zebra biomass, this is a typical food chain.

The amount of biomass and energy contained in living things always gets less at each stage of a food chain from plant onwards. So the amount of biomass in the plant will never be the same again. Only a small amount of the biomass is used for new animal material. 

What happens to the rest?

• When herbivores cannot digest all of the plant material they eat, the material is passed out in their faeces.
