Using the ten percent rule, each level of the food chain receives approximately 10% of the energy from the level below it.

  1. Starting with algae, which has 135,000 Kcal:
    • Shrimp (primary consumer): 10% of 135,000 Kcal = 13,500 Kcal
  2. For the lantern fish (secondary consumer), it would take 10% of the energy the shrimp receive:
    • Lantern Fish (secondary consumer): 10% of 13,500 Kcal = 1,350 Kcal
  3. Finally, for the tuna (tertiary consumer), it receives 10% of the energy from the lantern fish:
    • Tuna (tertiary consumer): 10% of 1,350 Kcal = 135 Kcal

So, according to the ten percent rule, the tuna will receive 135 Kcal of energy.

Thus, the correct response is: 135 Kcal.
