  In this work, we have studied accretion of dark energy (DE) onto Morris-
Thorne wormhole with three different forms, namely, holographic dark energy,
holographic Ricci dark energy and modified holographic Ricci dark energy .
Considering the scale factor in power-law form we have observed that as the
holographic dark energy accretes onto wormhole, the mass of the wormhole is
decreasing. In the next phase we considered three parameterization schemes that
are able to get hold of quintessence as well as phantom phases. Without any
choice of scale factor we reconstructed Hubble parameter from conservation
equation and dark energy densities and subsequently got the mass of the
wormhole separately for accretion of the three dark energy candidates. It was
observed that if these dark energies accrete onto the wormhole, then for
quintessence stage, wormhole mass decreases up to a certain finite value and
then again increases to aggressively during phantom phase of the universe.
