Energy Flow and the Ten-Percent Rule
Captions available
The idea
Energy flows through trophic levels one way and degrades at each transfer, per Bio 0612, with roughly ten percent of one level's energy converting to the biomass of the level above.
In practice
An energy pyramid narrows sharply from producer to top consumer, reflecting this large loss per transfer.
Where people slip
The ten-percent figure is a rough average, not a fixed law every ecosystem obeys exactly.
