PLEASE HELP ME I AM IN A BIG PROBLEM​

Answer 1

Answer:

A lichen is not a single organism; it is a stable symbiotic association between a fungus and algae and/or cyanobacteria. Like all fungi, lichen fungi require carbon as a food source; this is provided by their symbiotic algae and/or cyanobacteria, that are photosynthetic.

Answer 2

Answer:

A lichen is a simple slow-growing plant that typically forms a low crusty, leaflike, or branching growth on rocks, walls, and trees.
