What can the algae do that helps the lichen survive?
Because lichens enable algae to live all over the world in many different climates, they also provide a means to convert carbon dioxide in the atmosphere through photosynthesis into oxygen, which we all need to survive.
How can lichens be helpful or useful?
Lichens perform useful functions in nature. They provide shelter for other organisms. They also provide food for animals and materials that they can use to build their homes or nests. When lichens grow on rocks, the chemicals that they release contribute to the slow process of rock breakdown and soil formation.

Why do lichens change color?
In the absence of special pigments, lichens are usually bright green to olive gray when wet, gray or grayish-green to brown when dry. This is because moisture causes the surface skin (cortex) to become more transparent, exposing the green photobiont layer.
Is lichen a sign of clean air?
