1,350 Kcal

Answer 1

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

Given the energy available at the producer level (algae) is 135,000 Kcal:

1. The primary consumers (shrimp) would receive: \[ 135,000 , \text{Kcal} \times 0.10 = 13,500 , \text{Kcal} \]

2. The secondary consumers (lantern fish) would receive: \[ 13,500 , \text{Kcal} \times 0.10 = 1,350 , \text{Kcal} \]

3. The tertiary consumers (tuna) will receive: \[ 1,350 , \text{Kcal} \times 0.10 = 135 , \text{Kcal} \]

Therefore, the tertiary consumer tuna will receive 135 Kcal.

So the correct answer is: 135 Kcal.
