**Answer all 3 for brainliest** Can you explain the atomic reactions that occur in nuclear fusion?

Can you explain what a photon is and how it is made?

How does this impact life on Earth?

Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or the absorption of energy.

The photon is a type of elementary particle. It is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless, so they always move at the speed of light in vacuum,

photons are in light so yeah
