Who acts as a pioneering species in a xerarch succession?
This question was addressed to me by my college professor while I was bunking the class.
My question is taken from Ecosystem topic in chapter Ecosystem of Biology – Class 12
The correct option is (c) Lichens
For explanation: The first biotic community to invade a bare land or area is known as the pioneer community. In a xerarch succession, lichens in the temperate region act as pioneering species. Some examples of lichens are Rinodina, Lecanora, Parmelia, etc.
