Detailed explanation-1: -During primary succession on land, fungi and lichen are the most common pioneer species. They break down minerals in the rock to form soil, which allow subsequent communities to colonize the area.
Detailed explanation-2: -Pioneer species are producers, so are able to create their own food from only sunlight, water and air (photosynthesis). Over time, they break down the rock to create soil and help to provide a more hospitable environment.
Detailed explanation-3: -Pioneer species are hardy species which are the first to colonize previously biodiverse steady-state ecosystems. Some lichens grow on rocks without soil, so may be among the first form of life. The example includes bacteria, fungi, and lichens.
Detailed explanation-4: -Examples of pioneer species are lichens, algae, and fungi. These species are more tolerant and eventually contribute to the formation of the soil by breaking down rocks into smaller particles.
