According to the ecological pyramid and the 10% rule, energy is reduced by 90% with each trophic level. To find the energy in the primary consumer level from the tertiary consumer level, you multiply by 10 for each step back. From tertiary to secondary is 10 times more, and from secondary to primary is another 10 times more, resulting in 100 times more energy at the primary consumer level than at the tertiary level. Therefore, 50 kcal at the tertiary level corresponds to 5,000 kcal at the primary consumer level.
