Explanation:

First Question (Multiple Choice)

After a glacier melts, the area is a barren, rocky environment with little soil. Lichen are pioneer species that can colonize such harsh, newly exposed areas (like bare rock) as they can break down rock and start the process of soil formation, unlike grasses, pine trees, or shrubs which need more developed soil or a more established environment.

A glacier melting exposes bare rock with no prior soil or organic material, so it's primary succession. Primary succession occurs in an area where no soil or organic matter previously existed (like after glacier retreat, volcanic eruptions). So the first blank would be "primary succession" and the second blank would explain that it starts on bare rock (or similar reasoning about lack of pre - existing soil/organic matter).

Answer:

B. lichen

Second Question (Fill - in - the - Blanks)

Assuming typical ecological succession options (e.g., primary succession, because the glacier melting exposes bare rock with no pre - existing soil or organic matter, starting a new succession from scratch):
