The ecological succession is a slow change in the living community of the ecosystem along with the changes occurring in the non-living environment until the ecosystem attains stability.
The primary succession can be defined as the initial level of succession. This succession begins in the primitive environment. The soil develops after the weathering process of rocks.
The secondary succession begins in the region where life forms existed before and the area begin damaged by the catostrophic event like forest fire, earthquake and other type of calamities. Some remaining plant parts can give birth to the entire colony of plants.

I think.
A series of cell divisions that result in the formation of an embryo is called mitosis.
The nitrogenous bases placed in between the DNA double helix strands, like rungs on a ladder, are positioned there because of the hydrophobic effect and are stabilized by hydrogen bonding. The stability of DNA also relies on the interactions between the hydrogen bonds between bases, hydrogen bonds between bases and surrounding water, and base interaction between neighboring bases.
Hydrogen bonds are able to stabilize the DNA double helix by pairing up with their complementary base pairs (guanine with cytosine and adenine with thymine)
