true of false

This is true. Pioneer species are introduced to infertile soil so that the soil may become suitable for growing other plant species. These species do not rely heavily on soil; instead, they live on rocks and minerals. Moreover, they break down these rocks into soil so and eventually create a thicker layer of soil, allowing other plant species to inhabit the same region.
