Lichens grow extremely slowly. Lichens are able to survive extreme conditions.
What is the function of lichens?
There are several main functions of lichens. The very important main function of lichens is that they provide a mode of survival in very harsh environments where algae can't survive.

What are the properties of lichens?
Lichens are like fungi because they can keep from drying out, have protective walls, and absorb nutrients from the air. They are like algae in that they are producers and can use photosynthesis.
When do lichens grow?
Lichens need sunlight, water, nutrients from the air including dust and some nutrients from the substrate they grow on they are sensitive to sulfur dioxide there are fluffy lichens, crusty lichens, scaly lichens, leafy lichens etc
Do they have plant in the ARCTIC?
For the most part, no, however a few very hardy plants, such as lichens, can survive.
How can lichens survive in habitats so seemingly devoid of nutrients and under harsh physical condition?
Lichens are one of the first organisms to colonise a newly disturbed area and are a part of the first stage in plant succession. Like mosses lichens have a number of adaptations which allow them to survive seemingly nutrient free habitats. Lichens, unlike vascular plants can grow with very little nutrients. There are enough nutrients carried in rain water and dust to allow lichens to grow on rock faces etc.
How do lichens break down rock?
Lichens are very tough. They can grow were no other plant could survive. "When growing on mineral surfaces, some lichens slowly decompose their substrate by chemically degrading and physically disrupting the minerals, contributing to the process of weathering." from Wikipedia.
Why are lichens so unusual?
Lichens are unusual because they are made of two organisms, fungus and a green algae.
What eats lichen?
Lichens can be found all over the entire world. two animals that eat the Lichens are Caribou and Reindeer.
Why are lichens often able to survive in environments considered to be too severe for plants?
Lichens are able to survive in harsh environments because they have a symbiotic relationship between a fungus and an algae or cyanobacteria. The algae or cyanobacteria provide nutrients through photosynthesis, while the fungus provides structure and protection. This allows lichens to thrive in areas with poor soil quality, extreme temperatures, and low moisture levels where plants struggle to survive.
What will happen if a yak is moved to the Arctic?
Because Muskoxen can survive in the Arctic regions of Canada, Greenland and Alaska and providing there is grass, herbs and lichens to eat, maybe the Yak could survive
