Lava flows

These little mosses and lichens are the first beings to recolonise cooled lava flows, since they use their roots to hang on to rocks and live off just air, sun and rain. As they die and decompose, soil is formed, leading the way to more complex plants that can further break down the rocks and eventually turn all this back into soil.
