Lichens absorb water and minerals from the air. As a result, they are easily affected by pollution. Thus the presence of lichens are a good source of air quality for other organisms
i need to know the answer nor answer it
Lichens are organisms that can cause cracks in rocks by secreting acids that break down the rock surface. This can create new microhabitats for other organisms to grow, leading to changes in the environment.
When an environment is disturbed, changes are seen in more sensitive organisms before the effect become apparent in less sensitive species. These organisms, usually plants or microorganisms, are called indicator species or bio-indicators.
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.
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.
Lichens are symbiotic organisms consisting of a fungus and algae or cyanobacteria that can produce acids through the decay process. As lichens break down, they release acids such as oxalic acid, which can contribute to the weathering of rocks and other surfaces over time.
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.
Lichens do not have a binomial name like other organisms. They are actually a symbiotic combination of a fungus and an alga or cyanobacterium. The naming system for lichens involves listing both the fungal and algal/cyanobacterial partner.
Organisms are not isolated in their environment. Organisms must interact with other individuals of their own species, with other species, and with their physical environment. The study of the interactions between organisms and their environment is called ecology (Greek: oikos- house; logia- study). The study of ecology can encompass all aspects of Biology; from physiology to behavior, because any change within an organism has the potential to affect its relationship with the environment.

maintain balance of nature, and so others can use the nutrients when it is recycled.
