What do the lichens and mosses produce to break down rocks to begin the formation of soil ?

acids

nutrients

roots

soil

Acids

Explanation:

Lichens and mosses are the two plant species which belong to the plant kingdom Bryophyta. These are the two early species which colonize over a barren land. They make the environment suitable for the survival of other species. The Lichens firstly colonize over the rocks and they secrete acids which helps in the withering process of rocks into fine particles of soils. This facilitates the growth of small mosses. This helps in improving the quality of soil so that more plants can grow over it.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
