  In this paper, we study Riemannian submersions whose total manifolds
admitting a Ricci soliton. Here, we characterize any fiber of such a submersion
is Ricci soliton or almost Ricci soliton. Indeed, we obtain necessary
conditions for which the target manifold of Riemannian submersion is a Ricci
soliton. Moreover, we study the harmonicity of Riemannian submersion from Ricci
soliton and give a characterization for such a submersion to be harmonic.
