Answer:
The trophic efficiency between the primary and the secondary produces is 18.064 %
Explanation:
The trophic efficiency is the ratio or the fraction obtained by dividing the energy used for growth at a trophc level by the level of energy supplied at the the next lower trophic level.
The given parameters are;
The energy produced by the bacteria (primary consumer) = 173,000 kJ/(m²/y)
The energy contained in the plankton = 28,000 kJ/(m²/y)
The energy contained in the shrimp = 3,100 kJ/(m²/y)
The energy contained in the herring = 150 kJ/(m²/y)
Therefore, we have;
Energy supplied at the primary trophic level = 173,000 kJ/(m²/y)
The energy used for growth (contained) in the secondary trophic level (secondary consumer) = 28,000 + 3,100 + 150 = 31,250 kJ/(m²/y)
