Lichens
Lichens are the first organisms to appear in primary succession because they are able to colonize bare rock surfaces and begin breaking it down into soil through their ability to produce acids that break down minerals. Lichens are also able to survive in harsh environmental conditions, making them well-suited to establish themselves as pioneer species in the initial stages of primary succession.
The order of organism succession typically starts with pioneer species such as lichens and mosses, which can grow in harsh conditions. These are followed by grasses and shrubs, then trees, leading to a climax community with a stable and diverse ecosystem.
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.
After a glacier recedes, a volcano erupts, or a strip mine is abandoned.
Lichens
Algea and fungi grew and together produced lichens that were the first organisms during this succession. This prepared the area for further growth.

They eat willows, lichens and grasses.
Lichens are important in primary succession because they are one of the first organisms to colonize bare rock or soil, helping to break down rocks and create a healthy environment for other plants to grow. They can survive in harsh conditions and can trap moisture and nutrients, creating a microhabitat that supports other organisms. Lichens are also capable of fixing nitrogen, which enriches the soil and facilitates further plant growth.
More plants begin to grow. (Inetrmediate Community- Small plants, Lichens, Grasses, Shrubs, Poplar, Pine, Willow Trees. Etc.) Hope this helped you! :)

Lichens and pioneer species both live in harsh environments with minimal resources. They are among the first organisms to colonize a new or disturbed habitat. Both play important roles in ecosystem establishment and succession.
