Expert Answer

Grass? represents the producer level. They trap only 1% of the sun?l?i?g?h?t’s?????'?s energy falling on them. So, the energy available in ?g?r?a?s?s????? will be 1% of 10,000 J which will be 100 J.

????According to 10% law, at each trophic level about 10% of the energy of the previous trophic level is passed to the next trophic level.

Energy available to deer = 100 x 10/100 = 10 J

Energy available to lion = 10 x 10/100 = 1 J
