Question

The ‘10 Percent Law’ is related to

• A. Non-Mendelian genetics
• B. Mendelian genetics
• C. Energy consumption during photosynthesis in C₄ plants
• D. Energy transfer from a lower trophic level to a higher trophic level

Answer 1

The correct option is D

Energy transfer from a lower trophic level to a higher trophic level

The ‘10 Percent Law’ implies that exactly 90% of the energy is lost in the transfer at each trophic level, and that only 10% is passed on as biological energy. According to this law, during the transfer of energy from organic food from one trophic level to the next, only 10% of energy from organic matter is stored as flesh. The remaining is lost during transfer, broken down in respiration or lost to incomplete digestion by higher trophic levels.
