Answer 1

To apply the ten percent rule in energy transfer through trophic levels, we can consider the following path from producers to tertiary consumers:

1. Producers (Algae): 135,000 Kcal

2. Primary Consumers (Shrimp): They receive 10% of the energy from algae.
   \( 135,000 \text{ Kcal} \times 0.10 = 13,500 \text{ Kcal} \)

3. Secondary Consumers (Lantern Fish): They receive 10% of the energy from shrimp.
   \( 13,500 \text{ Kcal} \times 0.10 = 1,350 \text{ Kcal} \)

4. Tertiary Consumers (Tuna): They receive 10% of the energy from lantern fish.
   \( 1,350 \text{ Kcal} \times 0.10 = 135 \text{ Kcal} \)

Thus, the tuna receives 135 Kcal of energy.

Response:

135 Kcal
