Answer

B

Explanation

In lithosere (xerosere or xerach), the pioneer community is usually constiuted by crutose lichens (e.g., Graphis, Rhiocarpon ). Folisoe lichens (e.g., Dermatocarpon, Parmelia) kill the crustose lichens by shading them, cause deeper depression and accumulate more soil particles and organic matter. Foliose lichens make the conditions favourable for the growth of hardy mosses (e.g., Tortula, Grimmia).
