Answer 2

Why lichens are called pioneers of the plant cover?

Lichens are called pioneers of the plant cover because they are the first organisms to colonize bare rock surfaces. They are able to grow on bare rock and start the process of soil formation, which eventually allows other plants to grow in the area.

Lichens are a symbiotic association between a fungus and an alga or a cyanobacterium. This unique partnership allows lichens to survive in harsh environments, such as bare rock, where other plants cannot grow. As lichens grow and die, they contribute organic matter to the developing soil, which creates a suitable environment for other plants to establish themselves.

In addition to their role in soil formation, lichens are also able to fix nitrogen from the atmosphere, further contributing to the fertility of the soil and enabling the establishment of more complex plant communities.

Overall, lichens play a crucial role in the process of primary succession, where they are the first organisms to colonize a previously barren environment and pave the way for the establishment of a diverse plant cover
