The correct answer is "break down rock into soil." Pioneer species are the first organisms to colonize or inhabit a new or disturbed area. They play a crucial role in the early stages of ecosystem development. One of their primary roles is to break down rocks, which eventually leads to the formation of soil. As they grow and through their biological processes, pioneer species release organic matter, which helps in breaking down rocks and creating a suitable substrate for other plants to establish. This process is known as primary succession. So, by breaking down rocks into soil, pioneer species contribute to the development of a fertile ground for other plant species to grow and establish themselves in the ecosystem.
