Answer 1

The first thing to form in an ecosystem after an extreme disturbance is typically **a group of lichens**. Lichens are often pioneer species that can colonize bare substrates, such as rock, and begin the process of soil formation, which paves the way for other plants and organisms to establish themselves.
