Simple Description

A diagram that shows the amount of living energy at each stage of a food chain

Further Detail

Pyramids of biomass always decrease as they move up the food chain. This is because energy is transferred to the surroundings at each stage as heat or kinetic energy from respiration, as waste matter or remaining in uneaten parts of the organism e.g. roots or bones
