What is the 10 percent rule in the food chain

Answer 1

The 10 percent rule in the food chain states that only 10 percent of the energy from one trophic level is passed on to the next trophic level. This means that when energy is transferred from one organism to another, only 10 percent of the energy is available for the organism at the next level. This is due to the fact that the other 90 percent of the energy is lost as heat during the transfer.
