According to 10% law.

10% energy is transfered in consumer act of total energy.

Let be the energy of sheep = x

10% of plant's energy will transfer in sheep.

x=\frac{20000\; J\times 10}{100}

x=2000 J

10% of sheep's energy will transfer in Man,

so, energy of Man = 10% of sheeps energy

=\frac{10}{100}\times 2000

Man's energy = 200 J
