Ecological succession
The gradual and orderly process of change in an ecosystem due to the replacement of one community

Pioneer organism?
Species that initiate recovery of a land for example lichen, fungi, and mosses
How does soil develop after the ecosystem has been destroyed
Lichens and mosses break down rocks into soil
How do the numbers and types of organisms present in the community change over time
Small herbs appear and after years, animals return and. Small herbs are replaced by trees!
Secondary succession compare
Secondary succession has soil intact thus making it faster than primary
Climax community
