1,350 Kcal

Answer 1

The ten percent rule in ecology states that approximately 10% of the energy from one trophic level is transferred to the next trophic level.

In this case, the energy available at each trophic level is as follows:

1. Algae (Producers): 135,000 Kcal
2. Shrimp (Primary Consumers): 10% of 135,000 Kcal = 13,500 Kcal
3. Lantern Fish (Secondary Consumers): 10% of 13,500 Kcal = 1,350 Kcal
4. Tuna (Tertiary Consumers): 10% of 1,350 Kcal = 135 Kcal

Therefore, the amount of kilocalories of energy that the tertiary consumer tuna will receive is 135 Kcal.

The correct response is: 135 Kcal
