Here's why:
* Primary succession is the ecological process of change that occurs in an area that has never previously supported life, or where all life has been wiped out. Think of a newly formed volcanic island or a glacial retreat.
* Glaciers are powerful forces of erosion and leave behind bare rock and very little soil.
* Pioneer species like lichens and mosses will be the first to colonize the area, breaking down the rock and starting the soil formation process.
* Over time, more complex plant life will emerge, leading to a diverse and stable ecosystem.
This process is slow and can take hundreds or thousands of years, but it's an essential part of how life re-establishes itself after a major disturbance.
