Answer 1

After an extreme disturbance, the first thing to form in an ecosystem is typically **a group of lichens**. Lichens are hardy organisms that can colonize bare rock and soil, making them crucial for the process of primary succession. They help to break down the rock into soil, facilitating the growth of other plant communities over time.
