Question

According to Lindeman's 10% law, only 10% of energy is transferred to next trophic level. What amount of energy will be passed to next trophic level if plants produce 1,000kcal of energy?

• A. 10, 000 kcal
• B. 1,000 kcal
• C. 100 kcal
• D. 10 kcal
• E. 1 kcal

Answer 1

The correct option is C 100 kcal

Plants absorb 1% of sun energy for photosynthesis. With each trophic level, only 10% energy is transferred and 90% is lost as heat in respiration. If plants produce 1,000kcal of energy, primary consumers will obtain 10/100 x 1000= 100 kcal of energy. Thus, the correct answer is C.
