a lava flow
Primary succession occurs in an area where there is only bare rock - no organisms and no soil. This occurs after a volcanic eruption on land that covers an area in lava. It also occurs when a volcano at sea becomes tall enough to become a volcanic island.
It can take 10 to 100 years --Silvericy
New oceanic islands and new rocks formed by solidifying lava .
the lava flow is a density independent that flow good from the chemicals lava it have to flow and it is independent
a lava flow
after a lava flow
Primary succession starts on sites e.g. Sanddunes,lava flow.which have not previously borne vegetation
the lava and ash deposited during a volcanic eruption breaks down to provide valuable nutrients for the soil

Primary succession is one of two types of ecological succession and biological succession of plant life, and occurs in an environment in which new substrate, devoid of vegetation and usually lacking soil, is deposited (for example a lava flow). (The other type of succession, secondary succession, occurs on substrate that previously supported vegetation before a disturbance destroyed the plant life.) In primary succession pioneer species like mosses, lichen, algae and fungus as well as other abiotic factors like wind and water start to "normalize" the habitat.
Primary succession occurs, as any life will be incinerated or trapped under solid rock.
on sand, sand dunes, shingle, as well as bare rock and cooled volcanic lava.

"Succession is a process of ecological change in which a series of natural communities are established and then replaced over time. Ecologists (scientists who study the relationships of organisms with their living and nonliving environment) generally recognize two kinds of succession, primary succession and secondary succession. Primary succession takes place on an area that is originally completely empty of life. As an example, an area that has been covered by a flow of lava has, for a time, no life at all on it. Over a period of time, however, various kinds of organisms begin to grow in the area. Over time, the variety of life-forms changes as succession continues."
Primary succession begins in areas where no soil is present.Secondary succession occurs in areas where there is soil already present.Ecological succession refers to orderly changes in an ecological community. These changes may happenbecause of the start of a new empty habitat (after a landslide, glacier, nuclear explosion, lava flow or even concreting), where all traces of previous biological material, even soil have been wiped out (Primary), orby some sort of disturbance (like bush fires, harvesting or logging) of an already existing habitat, which is not severe enough to kill everything. So plants can regrow and seeds spring up again (Secondary).Primary succession's the succession taking place at a venue where no ecosystems has ever existed (300yrs) and secondary succession's a succession at a venue where an ecosystem was once established but deceased due to human impacts or natural disasters.
