Answer:
Fusion of hydrogen to helium
Explanation:
The sun produces its energy mainly by fusing hydrogen nuclei to form helium.
In the sun 4 hydrogen nuclei join to form one of helium, this fusion releases a lot of energy and because this fusion occurs in large quantities, this is where the energy of a star like our sun is produced, and that is the reason of its plasma state.
The energy produced in the fusion is received on earth in the form of electromagnetic radiation.
