A. Primary succession

Explanation:

The ecological succession is a gradual change that typically occur in the living community with respect to natural alteration occurring in the non-living factors of the environment until the ecosystem establishes stability.

A primary succession can be define as the successional change that occur in a region which was not inhabited by any species before. The region can be primitive the environmental factors are not favourable for supporting life initially.

In primary succession the vegetation like lichen may release acids which can weather the rocks leads to the formation of soil. The soil particles are necessary for the growth of plants. The lichen being the first species to grow over the land. Thus it may be called as pioneer species.
