carbon cycle diffusion definition
The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food.Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration.arbon is also found abundantly in our atmosphere in the form of carbon dioxide, or CO2. Additionally, carbon is also trapped within the Earth in the form of fossil fuels. The carbon cycle is essentially nature's way of reusing carbon atoms in different ways and in varying places.
