Explanation:

Question 2

In primary succession, the first organisms to colonize bare rock or other lifeless areas are pioneer species like lichens and mosses. They help break down the rock and form initial soil. Trees, shrubs, and grasses come later in succession.

Primary succession occurs in an area with no previous soil, like bare rock. Lichens and mosses colonizing bare rock is primary succession. A forest regrowing after a wildfire (secondary, as soil exists), grasses in an abandoned business (secondary, soil present), and a garden (human - maintained, not succession) are not primary succession[Client Connection Error] examples.

Secondary succession happens in an area where life was present before a disturbance (like a fire, flood, etc.) and soil remains. So when life returns to an area after a disturbance, it's secondary succession. Starting from scratch (no soil) is primary, plants regrowing or animals moving don't define secondary succession as well as the return of life after a disturbance with soil intact.

Answer:

c) Lichens and mosses
