Lichens, represented by this symbiotic relationship, are responsible for <u><em>primary succession</em></u> or the establishment of a new site for plant growth.
Explanation:
Primary succession can be described as a type of succession which occurs in areas where there was no form of life before or any form of life had fully been eradicated from those areas. For example, lava flow etc.
Lichens are the species which tend to colonize these lands first and are the pioneer species to be seen during primary succession. They have the capability to grow on rocks and release acids which break down the rocks and converts them into soil.
Migration can affect population distribution by causing the population of one area to increase while simultaneously decreasing the population of another. This can also cause one area to be more densely populated than another. ... High density of population.
