Carbon cycle is the movement of carbon from the atmosphere to the Earth.
Carbon move in the carbon cycle and start from the atmosphere.
In the atmosphere, carbon react with oxygen and it is inform of carbon dioxide. Plants use the carbondioxide along with water,and uses light energy from the sun to produce carbohydrates through a process of photosynthesis.

During respiration, carbon atoms are released to the atmosphere.
Some human activities like burning of fossil fuels releases carbon to the atmosphere.
Evolution is the change in an animal over time. Evolution causes this one animal to branch out into many different species of animals.
How evolution starts- There is a mutation in the genes of one animal. If the mutation helps the animal, than the animal breeds and passes on this mutation. This is natural selection. Natural selection is the starting point of evolution because all of the helpful mutations get passed down to change the species over time for the animals' benefit.
