If 20kJ energy is available at the producer level, then how much energy will be transferred to the lion in the food chain: Producer → deer → lion?
Options
- A0.2 k J
- B0.02 k J
- C0.002 k J
- D2 k J
Correct answer
A. 0.2 k J
Step-by-step solution
As per the Ten percent energy transfer law introduced by Lindeman-'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.' In a typical food chain, only ten percent of the energy is passed to the next consumer in the unidirectional manner. Since, producer has 20kJ, the deer will have 2kJ. Hence, the lion will only get 0.2kJ
