5.1 Pyramids of Biomass
Pyramids of Biomass
The source of all energy is the sun the light is photosynthesised by plants and some algae.Biomass is the mass of living material in plants and animals that is built up by energy from the sun.
Some of this light energy is stored as chemical energy in Green plants which is passed through a food chain or food web.
A pyramid of biomass shows the amount of energy at each stage of the food chain.
The pyramid of biomass get shorter as it goes up because not all of the organisms are consumed by the level above, some of the energy is passed out as waste from the organisms and some energy is lost through other means.
