Question 26
Growth of Lichens on barren rocks is followed by the growth of

(a) moss
(b) ferns
(c) gymnosperms
(d) algae

Answer 1

(a) moss

Lichens are the pioneer of succession which produces acid to erode the barren. Most lichens grow on stable rock surfaces or the bark of old trees. They are an important part of soil stabilization and help to retain water in the soil. This enables mosses to grow on the soil after lichen which is then followed by gymnosperms.
