According to the 10% rule, only 10% of the energy is transferred from one trophic level to the next. So, for every transfer of energy, only 10% is passed along. If 10,000 KCAL is the total amount of energy in the primary producers, only 10% of energy (1000 KCAL) will be passed to the primary consumers, and only 10% of that energy (100 KCAL) will be passed on to the secondary consumers, and so on. Therefore, only 1% of 10,000 KCAL (10 KCAL) will be transferred to third-order consumers.
