Moss (Bryophyta)

An example of moss. Moss isn't an example of parasitism (because the rock isn't living of course) and because it doesn't change the rock in any way. Moss is a plant, not a fungus. It grows and lives exactly like a plant, but is just in a different form.
Abiotic Factors: The rock, dead leaves, and soil
Biotic Factors: Moss, and the weeds
