The average trophic efficiency of transfer of energy from one trophic level to the higher trophic level is called
A
Assimilation efficiency
B
Exploitation efficiency
C
Lindemann's trophic efficiency rule
D
Gross primary production
Solution
The percentage of energy converted into biomass by a higher trophic level over the energy of food resources available at the lower trophic level is called ecological efficiency. It is also called Lindemann's trophic efficiency rule.
$E E=\frac{\text { Energy converted into biomass at trophiclevel }}{\text { Energy present } \in \text { biomassat lower trophiclevel }} \times 100$
