The types of species in a community gradually change and are replaced through a process known as ecological succession.

<h3>Ecological succession </h3>

The process by which a region's species and habitat mix needs to evolve over time is called ecological succession. These communities gradually replace one another until a "climax community" is reached, such as a mature forest, or until a disturbance, such as a fire, happens. A key idea in ecology seems to be ecological succession.

On the island, ecological succession has produced topsoil that can support ecosystems. As shrub/grassland areas change into forested areas during ecological succession, there are different types of habitat fragmentation.

If a carbon atom is bonded to two hydrogen atoms and two carbon atoms, what type of bond must exist between the carbon atoms?

makkiz [27]

<u>Answer:</u> A single covalent bond is present between the carbon atoms.

<u>Explanation:</u>

Carbon is the 6th element of the periodic table. The electronic configuration of this element is: $1s^22s^22p^2$

This element has 4 valence electrons and to attain stability, it cannot gain 4 electrons nor it can loose 4 electrons. Thus, it has to share 4 electrons in order to attain stability. Thus, this element forms covalent bond.

A covalent bond is formed by the sharing of electrons between two atoms.

In the question, it is given that carbon is bonded to 2 hydrogen atoms and two carbon atoms. Thus, the bond between the carbon atoms will be a single covalent bond.
