Question

Lichens are called pioneer colonizers of bare rock. How can they help in the formation of soil?

Answer 1

Lichens:

1. Chemical compounds produced by lichens break down rocks into smaller bits, resulting in soil formation.
2. They increase the fertility of the soil by trapping water, dust, and silt.
3. Lichens decompose in the soil, adding organic matter that increases the soil's ability to support other plants.
4. Crustose Lichens can be found on naked rocks, stone, and other similar surfaces.
5. Chemical compounds are released, causing small fragments of rock to break up and minerals to be liberated, which they absorb.
6. This marks the beginning of the transition of rock into fertile soil, allowing various plant groups to flourish.
