1. hydrogen atoms crash together
Hydrogen atoms (or protons) fuse within the Sun core and fall apart.
2. helium atoms are formed
Helium atom is a product of the proton-proton fusion and this process occurs through a series of steps.
3. an enormous amount of energy is released
The transformation that occurs after the fusion results in a release of huge amount of energy that keeps the sun hot. Energy is radiated out from the core of the Sun
4. energy travels to Earth in the form of light energy and heat
This energy is called The Solar energy to the Earth because it hits the surface of the Earth itself.
5. plants will use energy from the sun to make their own food
Plants are phototrophic organisms that transform the light energy into usable energy for their metabolism.
Carbs contain lots of energy, so not A.
They are different carbs with different atom arrangements, so not B.
And carbs only contain 3 elements C, H, and O.
So the answer should be C.
