60 pointz will give brainiest if correct what best describes what happens during stellar fusion in a main sequence star. a one step process where one atom of helium is generated from four atoms of hydrogen. a complex process from which all the elements of the periodic table are formed. a three step process from which hydrogen fuses to helium, which fuses to carbon, which fuses to silicon a three step process where one atom of helium is generated from six atoms of hydrogen, returning two atoms of hydrogen to the stellar core.

Answer by Mimiwhatsup: A one step process where one atom of helium is generated from four atoms of hydrogen.

Why: "Hydrogen fusion (nuclear fusion of four protons to form a helium-4 nucleus) is the dominant process that generates energy in the cores of main-sequence stars. It is also called "hydrogen burning", which should not be confused with the chemical combustion of hydrogen in an oxidizing atmosphere." (Wikipedia)

i think the answer is b.

more words for this could be abiotic and biotic

abiotic: living organisms within an ecosystem

biotic: non-living organisms within an ecosystem
