The entanglement entropy approach to study the dependence of entropy upon the location of degreesof freedom (dof ) (near/far) from the horizon is discussed in this article. We try to understand thephysical deviation of the area law for the excited states by incorporating the logarithmic and powerlaw corrections. We show that the dof near the horizon gives contribution to the total entropy ofthe system in the ground state and away from the event horizon gives contribution to the excitedstate.
