Scientists call an area of all one species a monoculture. A field of corn or any other crop is a monoculture. The average lawn is also a monoculture. The biodiversity is very low. Write a scientific explanation describing the advantages of a polyculture forest (high diversity).

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
