Text Solution

Verified by Experts

The correct Answer is:
B
A lithosere (a sere originating on rock) is a plant succession that begins life on a newly exposed rock surface such as one left bare as a result of glacial retreat, tectonic uplift as in the formation of a raised beach or volcanic eruptions spores of lichen or fungus being the pioneer species are spread onto a land of rocks. Then the rocks are broken down into smaller pieces and organic matter gradually accumulates favouring the growth of larger plants like grasses, ferns, and herbs.
