Answer 1

After an extreme disturbance, the first thing to form in an ecosystem is typically **a group of lichens**. Lichens are able to colonize bare rock and are often one of the first organisms to establish in a disturbed area, contributing to soil formation and paving the way for other plant communities to develop.
