Question

The loss of energy as one proceeds from one trophic level to the next higher level is approximately :

• A. 30- 35 %.
• B. 40- 45%.
• C. 60- 65%.
• D. 90- 95%.

Answer 1

The correct option is D 90- 95%.

According to 10% law, during the transfer of energy from one trophic level to the next higher level, about 10% of the energy from organic matter is saved and the remaining is lost as heat or broken down in respiration. Therefore, it can also be said that 90-95% energy is lost while transfer from one level to the higher level.

So, the correct answer is option D - '90- 95%'.
