Primary Seccession has a larger effect biodiversity.
Why?

Poop

As the pioneer species alters the environment, it makes it more suitable for other organisms to colonies. When they colonies the environment it is changed again which further makes the environment more suitable to a wider range of organisms, increasing biodiversity.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
