Final answer:
Pioneer species in primary succession help create soil for other species to thrive and contribute to ecosystem development.
Explanation:
Pioneer species play a crucial role in primary succession by being the first to colonize an area with minimal soil, such as after a volcanic eruption. These hardy plants and lichens help break down rock into soil, paving the way for other species to grow. As pioneer species grow, die, and decompose, they contribute to soil formation and create conditions for a diverse ecosystem to develop over time.
