Answer & explanation:
Primary succession occurs in environments that did not have biological communities in place and present unfavorable conditions for the establishment of life. Examples of these sites are rocks, dunes and newly solidified lava pits.
The pioneer organisms in primary succession are mainly producers and some decomposers.
In <u>dune</u> <u>environments</u>, for example, there are grasses, whose seeds are wind-borne and able to withstand excessive heat, water scarcity and unstable soil, and their roots are firm, preventing these plants from being harmed by the wind.
Sites with <u>rocky</u> <u>surfaces</u> can be colonized by photosynthetic bacteria, fungi or some species of algae. These organisms release substances that alter the substrate, allowing the installation of new species over time.

Well by the nature of science itself , we know that it is a rapidly progressing area . So , scientific laws are basically ideas from theories , it does not mean that it is absolute , because future research of that same topic on which the law is based , can always change and thus the theory and thus the law. So , scientific laws and theories change over time due to new phenomena and scientifc research that gives a more accurate theory than the old laws and theories.
