Question

According to a pyramid of production, approximately what percent of the energy at a trophic level is transferred to the next trophic level?

• A. 2%
• B. 10%
• C. 50%
• D. 75%
• E. 90%

Answer 1

The correct option is B 10%

The number of trophic levels in the food chain is restricted as the transfer of energy follows 10 percent law. This law states that only 10% of the energy is transferred to each trophic level from the lower trophic level.

According to Lindeman's Law of trophic efficiency, the efficiency of energy transfer from one trophic level to the next is about 10%. Lindeman considered individual organisms belongs to trophic levels with each level acting as a transformer of energy.

So, the correct answer is 10%.
