Ecological succession is the gradual replacement of populations in a habitat. This here is the first stage of primary succession. That volcano erupted, and now, there is no soil and there are only rocks, which are abiotic. This was the deciduous forest, but now it's just rocks everywhere. The sustainability of this environment is now low. Click To EditEcological succession is the gradual replacement of populations in a habitat. This here is the first stage of primary succession.

Yes, you are right! Now, the only life that can sustain on these rocks are pioneer species, which are organisms that do not need soil to grow. One example of this are lichens.
Way to go, about 20 years have passed! Now, we are in the second stage, the soil building process. Opposed to secondary succession, soil and dirt need to be formed in primary succession because it starts out with rock.
Yes! Since primary succession starts with rock, is has slow changes compared to secondary succession, which has faster changes. The lichens and mosses have weathered and broken down the rock to create the soil and dirt.
Wohoo! Now we are in the third stage (25th year), where grasses and bushes, which are producers, start to grow! Some consumers, such as small insects, which are biotic, are finally coming back!
Hello there! The ecosystem and environment are coming back to life, and the various communities are beginning to be restored!
Oh, some small trees are growing now! smaller animals such as hedgehogs and mice are starting to show up! The biodiversity and animal populations are coming back!
Yes! The weathering of the rocks and the growth of plants finally led to this stage. We are now in the 100th year! We are getting closer to climax community!
Look now, we are in the 200th year! There are tall trees that have grown. Hooray! This ecosystem is growing back from a major natural disaster, a volcanic eruption!
Yes indeed! Now, larger animals, like wolves, are living in this ecosystem!
My home is back!
The deciduous forest is now at the state of homeostasis, which means it is now a balanced ecosystem!
This process took about 300 years to be complete, and here we are now!
