Energy Transfer in a Food Chain

Algae
Shrimp
Lantern Fish
Tuna
135,000 Kcal


1,350 Kcal

135,000 Kcal

135 Kcal

O 13,500 Kcal

Answer 1

Tuna (tertiary consumer) receives 135 Kcal.

Reason: using the 10% energy-transfer rule:
- Algae: 135,000 Kcal
- Shrimp (primary consumer): 135,000 × 0.10 = 13,500 Kcal
- Lantern fish (secondary): 13,500 × 0.10 = 1,350 Kcal
- Tuna (tertiary): 1,350 × 0.10 = 135 Kcal
