The carbon cycle is the flow of carbon in the spheres of the planet. Return of $\rm CO_{2}$ to the atmosphere by burning organic matter has the greatest impact.

What is the impact of the carbon cycle?

The carbon cycle is the continuous flow and the movement of carbon and its compounds in the atmosphere and the other spheres of the planet. The ancient organic matter is the fossil fuels that are used as energy sources for various purposes.

The burning of the fossil fuels like coal, petrol and diesel are used as power sources to drive machines, vehicles and engines. The burning of these fossil fuels leads to the release of a large amount of carbon dioxide in the atmosphere and increases its concentration in greenhouse gases.

This increase in the carbon dioxide in the atmosphere leads to global warming as the increased concentration of these gases leads to a rise in the temperature of the planet's surface.

Therefore, option C. return of the carbon dioxide to the atmosphere will have the greatest impact.

Hello!

The part of the carbon cycle where humans had the greatest impact is the return of CO₂ to the atmosphere by burning of ancient organic matter.

The ancient organic matter is also called Fossil Fuels. Some Fossil Fuels are Petroleum and Coal. Fossil Fuels are used to power our society and are burned to provide energy for power plants and vehicles, and by burning them, Carbon Dioxide (CO₂) is produced, increasing the natural concentration of this compound in the atmosphere.

Have a nice day!
