It is when a species is introduced into a new area. It could be caused by humans moving species or migration.
The communities in a successional sequence of primary succession?
Primary Succession
primary succession
It depends on just where the ecosystem is located.
The succession shown in the animation is primary succession because it starts on bare rock with no soil present. Primary succession occurs in areas where no soil exists, such as on rocks formed after a volcanic eruption or glacial retreat.

The succession shown in the animation is primary succession because it starts on bare rock with no soil present. Primary succession occurs in areas where no soil exists, such as on rocks formed after a volcanic eruption or glacial retreat.
Because then there is life in the ecosystem
In secondary succession, there may be remnants of soil and organic matter left over from the previous ecosystem, which is not typically present in primary succession. This can provide a foundation for plant growth and help jumpstart the regeneration of the ecosystem.
Because then there is life in the ecosystem
The parts of the ecosystem that had to be established before the primary succession shown in the transparency could occur is the lichens, rocks and soil...also that the mosses, ferns, shrubs, and grasses are parts of the primary succession.
because it needs time to heal
Primary succession typically takes longer than secondary succession. This is because primary succession occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption or glacial retreat, requiring a longer time for soil development and ecosystem establishment. In contrast, secondary succession happens in areas where a disturbance has cleared an existing ecosystem but left the soil intact, allowing for faster recovery and regrowth.
