In a food chain of Grass - Deer - Leopard, if 1000 Joules of energy is available at the producer level, then how much energy will be received by leopard ?

Options

  1. A1000 Joules
  2. B100 Joules
  3. C10 Joules
  4. D1 Joules

Correct answer

C. 10 Joules

Step-by-step solution

According to the 10 % law of energy transfer proposed by Lindeman, only 10 % of the energy available at one trophic level is transferred to the next trophic level. The given food chain is: Grass Deer Leopard. Energy available at the producer level (Grass) = 1000 Joules. Energy transferred to the primary consumer (Deer) = 10 % of 1000 Joules = 10 100 1000 = 100 Joules. Energy transferred to the secondary consumer (Leopard) = 10 % of 100 Joules = 10 100 100 = 10 Joules. Thus, the energy received by the leopard is 10
