which of these are common to hydrach succession and xerach succession
Answers
Answer:
Differences
Hydrarch successions takes place in watery areas where as xearch successions take place in dry areas.
Hydrarch successions takes place in series from hydric to mesic conditions whereas xearch successions takes place from xeric to mesic conditions.
Hydrarch successions start from phytoplankton stages whereas xearch start from bare rocks.
Similarities
Both hydrarch and xearch successions lead to medium water conditions and wet conditions.
Both end at forest and both lead to mesic conditions.
Answer:
Hydrarch succession takes place in ponds or any other water areas. There is progression from hydric conditions to mesic conditions. Xerarch succession takes place in dry areas (such as bare rock surfaces) and there is progression from xeric conditions to mesic conditions.
Hence, in both hydrarch and xerarch, mesic conditions i.e. medium water conditions are achieved. So, the correct answer is 'Medium water conditions'.
