Question

a process that occurs in a lifeless area lacking soil
a process that occurs in an ecosystem that has been disturbed but the soil is still in place
an organism that grows on rocks that and helps form soil
the first plants to grow during succession
the final, stable community reached during the stages of succession
a series of predictable changes that occur in a community over time is

pioneer species
lichens
primary succession
climax community
ecological succession
secondary succession

Explanation:

Each term is matched to its definition based on ecological succession concepts:

1. Primary succession is defined as colonization of lifeless, soil-free areas.
2. Secondary succession occurs in disturbed areas with intact soil.
3. Lichens are organisms that grow on rocks and break them down to form soil.
4. Pioneer species are the first organisms to establish during succession.
5. Climax community is the final, stable end state of succession.
6. Ecological succession is the overall term for predictable community changes over time.
