the end results of mitosis and meiosis are completely different: Mitosis: One diploid cell → two diploid cells. Goal is cell division. Meiosis: One diploid cell → four haploid cells.
When a previously occupied area gets colonized by a new dominant group of species or communities, this is known as secondary succession. In secondary succession, new residents take the place of earlier groups in a habitat that has been affected by an ecological disturbance.
