Identify The Symbiosis

             A lichen is a mutualistic relationship between algae and fungi. The lichens use sunlight energy, carbon dioxide, and water to make sugars and oxygen for the use of the fungi and algae. A weird fact is that if you were to send a lichen  to Mars the lichen would thrive because of the high amount of carbon dioxide on mars.http://www.redcolony.com/art.php?id=0109020#Lichen
