Detailed explanation-2: -Common examples of pioneer species include bacteria, lichen, mosses, and fungi. In the ocean they can be phytoplankton, zooplankton, and algae.

Detailed explanation-3: -Examples of Pioneer Species. Lichens, fungi, bacteria, fireweed, grasses, alder, and willow are examples of pioneer species.
