Yes. Lichens can contribute to the weathering of rock and the formation of soils.
Though previously suspected but now widely accepted that lichens can contribute to the weathering of rock and the formation of soils.There major long-term role has been as biological weathering agents, with a pedogenic action which is both physical and chemical in nature. The physical action of weathering is through penetration by rhizenae and expantion and contraction of thalli, and / or chemical, due to caron dioxide, oxalic acid, and the complex action of lichen substances.

Why are lichens especially well adapted to play the role of organisms in an ecological succession?
Lichens and mosses get mostly replaced by larger plant species during succession because, larger plants compete for resources like space, sunlight, and soil nutrients more succesfully, than moss and lichens.
What organisms grow on rock or exposed soil?
Mosses and Lichens, and possibly mushrooms
How do mosses and lichens help to from soil?
Lichens and mosses help to form soil by breaking down the rocks that they are attached to.
What role does lichen play in primary succession?
The lichens and mosses help to form soil by secreating acids on the rocks they cling to, also when lichens die they create soil so that one day the soil can support grasses that can support brushes and shrubs which can support, red alders then doug firs then cedars and hemloch
What are the charateristics of ecological succession?
The basic thing to know, is the primary succcesion occurs w/o any dirt presnt. The pioneer species, lichens and mossess, break down any rocks present to create soil. Secondary succesion occurs when there is already soil present, but the land has been cleared, like after a fire.
What helps soil by releasing acids that break down rock?
i think mushrooms :/ or lichens
How are lichens helpful?
For many animals, including caribou and musk oxen, lichens are an important food source. Lichens are also important in the weathering process of rocks. They grow on bare rock and release acids as part of their metabolism. The acids help break down the rock and as bits of rock accumulate and lichens die and decay, soil is formed. They are important in the primary succesion.They don't need to survive with soil.

Why are lichens often the first organism to be established in primary succession?
yes, The lichens and mosses help to form soil by secreating acids on the rocks they cling to, also when lichens die they create soil so that one day the soil can support grasses that can support brushes and shrubs which can support, red alders then doug firs then cedars and hemloch
How is soil formed by?
soil is formed by weathering because the bigger rock break the little rock and makes soil.
How do lichens contribute to soil formation?
Lichens work by picking up nutrients to help them produce and also pick up water to help the grow and live longer.
What forms when Rock's break down?
soil
How do mosses and lichens help to from soil?
Lichens and mosses help to form soil by breaking down the rocks that they are attached to.
Soil is formed from?
soil is formed by weathering because the bigger rock break the little rock and makes soil.
How does rocks break down?
It when water goes into the rock and then the water freezes and break the rock
