Using the ten percent rule, determine how many kilocalories of energy the tertiary consumer tuna will receive.
Algae | shrimp | Lantern Fish | Tuna |

A.) 135 Kcal
B.) 1,350 Kcal
C.) 135,000 Kcal
D.) 13,500 Kcal
The ten percent rule states that only 10% of the energy from one trophic level is transferred to the next trophic level.
In this case, the energy available at the shrimp trophic level is 135,000 kcal.
To find the energy available at the tertiary consumer tuna trophic level, we need to multiply the energy at the shrimp trophic level by the 10% transfer efficiency.
Energy available at the tertiary consumer tuna trophic level = 135,000 kcal * 0.1 = 13,500 kcal
Therefore, the tertiary consumer tuna will receive 13,500 kilocalories of energy.
The correct answer is option D) 13,500 Kcal.
