Solution

The correct option is A 0.03J
  • According to the Lindeman law, during the transfer of energy from one trophic level to the next, only about ten percent of the of energy is passed to the next trophic level.
  • Here, in this case, the plant traps 30J of energy. Of this only 10% i.e., 3J is getting absorbed by the mice.
  • From mice, only 10%, i.e., 0.3J is absorbed by the snake. And from here, only 10% will be available to peacock which is 0.03J.
  • Thus, the correct answer is option A.
