Primary Succession
Primary Succession:
This occurs in lifeless areas-- such as regions where the soil is incapable of sustaining life as a result of lava flows, newly formed sand dunes, or rocks left from retreating glaciers. But this area is later replaced by a new substrate that is adaptable to less-austere conditions, thriving on soil and minerals. The very first species to inhabit this habitat is known as the "pioneer species". The stable ecosystem that results is known as a "climax community".
