उत्तर
In the given food chain, it is mentioned that the amount of energy available to the plants is 20,000 J. As we know that according to the ten percent law, only ten percent of the total energy at one trophic level is available for use to the next trophic level. So, the amount of energy available to the sheep is 2000 J, andamount of energy available to the man is 200 J.
