Question

Which of the statements best describes Lindeman's Law?

• A. There is 100 percent transfer of energy between trophic levels
• B. There is only 10 per cent of the energy entering a particular trophic level
• C. At each trophic level there is 20 percent of energy lost as heat
• D. There is 2 - 10 percent energy transfer at each trophic level

Answer 1

The correct option is B There is only 10 per cent of the energy entering a particular trophic level

During the transfer of energy through successive trophic levels in an ecosystem, there is a loss of energy all along the path. No transfer of energy is 100 per cent. Lindeman in the year 1942 proposed the 10 percent law. According to ten percent law, only 10 per cent of the energy entering a particular trophic level of organisms is available for transfer to the next higher trophic level.
