Both, hydrarch and xerarch successions lead to
medium water conditions
xeric conditions
highly dry conditions
highly dry conditions
A.
medium water conditions
Hydrarch succession takes place in water areas and the successional series progress from hydric to the mesic conditions. As against the xerarch succession takes place in dry areas and series progress from xeric to mesic conditions. Hence, both hydrarch and xerarch succession lead to medium water conditions (mesic)-neither too dry (xeric) nor too wet (hydric).
