What organisms are usually the pioneer species in a new area how do these organisms prepare the area for other species?
Pioneer species are usually lichens and mosses which can grow on bare rocks. As they grow the lichens and mosses help break up the rocks to form soil. When these organisms die they provide nutrients that enrich the developing soil. Over time seeds of plants land in the new soil and begin to grow.
