10 percent of energy is transferred from trophic level to another trophic level.
On average, only 10 percent of energy stored as biomass in a trophic level is passed from one level to the other level. This is known as “the 10 percent rule” while on the other hand, 90 percent of energy is lost in the atmosphere in the form of heat energy. It limits the number of trophic levels an ecosystem can support. If a producer have 10000 energy units so 1000 energy units will be transferred to the primary consumers.
So we can conclude that 10 percent of energy is transferred from trophic level to another trophic level.
