Answer 1

it is primary succession i think

Answer 2

2.primary succession

Step-by-step explanation:

• The process by which the structure of the species population in an ecosystem changes with time is known as ecological succession.
• Primary succession is a type of succession which begins on barren land which was previously unoccupied by any living organism.
• As the glacier retreats and leaves behind rocky barren land it is clear that there was no existing living organisms that occupied this land and the succession will have to start from scratch, thus this is an example of primary succession.
