Question

If first trophic level represent 100,000 kcal of energy. According to Lindman's law, how much energy is available to the fourth trophic level?

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

Answer 1

The correct option is B 100 kcal

If first trophic level represents 100,000 kcal of energy, in second level it will have 10% of 100000 = 10000 kcal.

In third level, 10 % of 10000 = 1000 kcal

In fourth level, 10% of 1000 = 100 kcal

The Ten percent law is the transfer of energy from one trophic level to the next was introduced by Raymond Lindeman (1942). According to this law, during the transfer of energy from organic food from one trophic level to the next, only about ten percent of the energy from organic matter is stored as flesh.
