In the atmosphere, carbon is in the form of carbon dioxide.
Animal to soil
Carbon is removed from the atmosphere and into plants through a process called photosynthesis.
Soil to atmosphere
The plant that had carbon in it was eaten by an animal.
How humans are affecting the carbon cycle
When the animal dies the carbon returns to the soil and turns into fossil fuels.
R.I.P
When humans burn fossil fuels to power factories, power plants cars, etc. most of the carbon enters the atmosphere.
When humans cut down trees and overharvest plants less photosynthesis occurs, so less oxygen is being released and fewer Co2 levels are being absorbed.
