Answer:
Early colonizer role
Explanation:
Ecological succession refers to changes in the structure of components species of an ecological community over a period of time which can be as low as a decade or as large as millions of years.
Succession is divided into 3 main stages;
- primary succession
- secondary succession
- climax/stable community
Primary succession occur when living organism colonize an area that holds no life at all. The colonizing living organisms are therefore referred to as <em>pioneer species. </em>They colonize the new area and kickstart the various ecological processes that make up a community.
Secondary succession occur when the living organisms inhabiting a community are gradually replaced by new species of organisms.
Climax community is a stable or minimally changing ecological communities.
<em>Hence, pioneer species are early colonizer of a newly areas that hold no previous life. They kickstart the various ecological processes that constitute an ecological community such as soil formation, nutrient cycling, and primary productivity.</em>
