Using the ten percent rule, determine how many kilocalories of energy the tertiary consumer tuna will receive.

Question

Algae Shrimp Lantern Fish Tuna
135,000 Kcal

Answer 1

According to the 10% rule, only 10% of the energy is transferred from one trophic level to the next.

So, the energy available to the tertiary consumer (tuna) would be:

135,000 kcal x 0.10 = 13,500 kcal

Therefore, the tertiary consumer tuna will receive 13,500 kilocalories of energy.
