Both, hydrarch and xerarch successions lead to
Highly dry conditions
Excessive wet conditions
Medium water conditions
Xeric conditions
Hydroch succession occurs in aquatic areas and the order of succession develops from hydrous to mesic conditions. Unlike the dry season, succession occurs in arid regions, with the sequence shifting from arid to intermediate conditions. Thus, successions of hydrarch and xerarch result in conditions of mesic (mesic) humidity – neither too dry (xeric) nor too wet (hydric). Hence, option 3 is correct.
