Lichen is a fungus that is associated with another living organism such as an alga, the bark of a tree … It is said to live in symbiosis. That is to say, both help each other to survive.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Lichen grows where other plants cannot live: on top of the mountains, on rocks by the sea, on cooled lava and sometimes on sidewalks. They are easily recognized by their yellow\/green color and their round shape is flattened.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

It is also thanks to this round shape that researchers can get an idea of the period of history to which an object belongs.<\/p>\n

Indeed, the Arctic lichen, which can live for more than 10,000 years, grows by 1 mm every 50 years. This is how the stone statues of Easter Island (South Pacific) could be dated.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
