A) only 20% of the energy is transferred to each trophic level
B) only 10% of the energy is transferred to each trophic level
C) only 30% of the energy is transferred to each trophic level
D) only 50% of the energy is transferred to each trophic level
Correct Answer: B
Solution :
Reynold Lindemann (1942) for the first time gave energy transfer law, which states that only 10% of energy (of net primary productivity) is transferred from one tropic level to another, i.e., about 10% of organic matter is stored as flash of organism in each tropic level during transfer of organic food from previous tropic level. In other words the net productivity of the next higher tropic level shall be 10% of the first one.
