Detailed explanation-1: -Lichens are the pioneer species. They secrete acids to dissolve rock, helping in weathering and soil formation.
Detailed explanation-2: -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.
