Primary succession is the type of succession that occurs on bare rock or surfaces that have never been colonized before. In this scenario, the lava flow has completely denuded the mountain, leaving only bare rock, which means that no organisms exist in the area. As a result, primary succession will occur as the first organisms to colonize the area will be pioneer species like lichens and mosses that can grow on bare rock. Over time, these pioneer species will break down the rock and add organic matter to the soil, allowing for other plants and animals to gradually move in and establish a more complex ecosystem.
