lichen
The symbiotic association of a true fungi and a green alga. The alga makes sugar through photosynthesis, and the fungi fills out the organism while holding it to a surface (rocks, bark, etc. ). Lichens pioneer harsh or sparse environments, provide food for grazers, and break down rocks through chemical weathering.
