A primary succession is when new soil needs to be formed from the rocks whereas in secondary succession, the soil for new plants and life is already there in the ashes.
The Primary succession can be defined as an area that was not occupied earlier, barren, and uninhabited and there was no vegetation.
The secondary succession can be defined as the area in which previously there is a growth of a community and it is occupied, inhabited and has primary vegetation but it was got disturbed due to some external or internal factors.
Example of primary succession: Bare rock,Volcanic eruption, and Desert, while that of secondary succession will include earthquake, flood, forest fire etc
meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes. when two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes
