During primary succession it is the competition of resources that leads to changes/replacement of species in area over time

During Primary Succession, an area that has just been newly exposed or is rock that has just formed newly, gets colonized for the first time by organisms.

This is not driven by competition for resources because only certain organisms can even survive in the area in the first place such as lichens or plants which then convert the area to a more habitable form for other organisms over a period of centuries.
