Explanation:
Detailed explanation-1: -The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.
Detailed explanation-2: -Pioneer species pave the way for more complex communities of organisms because the pioneers have altered the physical environment to make it more habitable. This leads to other forms of ecological succession. Once grasses and weeds begin to grow, soil formation is accelerated and more animal species begin to appear.
