Xerarch succession ultimately leads to medium water conditions or mesic conditions

Q. Assertion: Xerarch succession ultimately leads to mesic conditions.
Reason: Xerarch succession begins on rocks.

Q. Complete the given analogy

Hydrarch succession : progresses from hydric to mesic conditions :: Xerarch succession: ___________

Q. Identify the correct statements regarding succession of plants.
(i) xerach succession leads finally to mesic conditions
(ii) primary succession is faster than secondary succession
(iii) bryophytes are generally the pioneer species for primary succession on rocks

Q. Identify the wrong pair of statements
I.During plant succession some species colonise an area and populations becomes more numerous whereas populations of other species decline and even disappear
II.Both hydrarch and xerarch successions lead to mesic conditions
III. Secondary succession is a slow process as compared to primary succession
IV.In successive seral stages there is no change in the diversity of species of organisms
