How do fossil fuels play a role in the carbon cycle?

The fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Fossil fuels are rich in carbon, and burning them returns carbon to the soil.
Fossil Fuels require a lot of carbs in to burn, which takes carbon out of the atmosphere
Fossil fuels require a lot of carbon to burn, which releases carbon into the atmosphere

The correct answer is: Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.

When fossil fuels such as coal, oil, and natural gas are burned for energy, they release large amounts of carbon dioxide (CO2) into the atmosphere. This process adds to the overall concentration of CO2 in the atmosphere, contributing to the greenhouse effect and climate change. Fossil fuels are formed from the remains of prehistoric plants and animals that accumulated carbon over millions of years. By burning these fuels, we are essentially releasing the stored carbon back into the atmosphere, disrupting the natural balance of the carbon cycle.
