Question

What is the role ofa pioneer species in primary succession​

Answer 1

The role of a pioneer species in primary succession is to normalize the habitat by making the topsoil more stable and fertile. Explanation; -In primary succession pioneer species like lichen, algae and fungi as well as other abiotic factors like wind and water start to normalize the habitat.

Answer 2

Answer:

The term pioneer is used to describe the species that first colonize new habitats created by disturbance. Although the term is usually applied to plants, microbial and invertebrate pioneer species are also sometimes recognized. For terrestrial habitats two groups of pioneers can be distinguished: those that colonize sites lacking developed organic soil and initiate primary succession and those that initiate secondary succession, often via recruitment from propagules in the soil. Pioneers of primary succession must cope with unfavorable conditions for establishment, and their growth and distribution is often restricted by available nutrient supply as a consequence of limited soil development. In contrast, pioneers of secondary successions often encounter resource-rich environments where competition with existing vegetation is reduced. Some of the fastest-growing plant species are pioneer herbs and shrubs, many of which have become important weeds in agricultural systems.
