Final answer:
Fossil fuels are the biggest contributor of carbon into our atmosphere. Other contributors include animals, plants, and bacteria.
Step-by-step explanation:
Fossil Fuels are the biggest contributor of carbon into our atmosphere. When we burn fossil fuels such as coal, oil, and natural gas for energy, carbon dioxide (CO2) is released into the atmosphere. This is because fossil fuels are made up of carbon and when they are burned, the carbon combines with oxygen in the air to form carbon dioxide.
Other contributors to carbon in the atmosphere include animals through respiration and decomposition, plants through photosynthesis and respiration, and bacteria through the breakdown of organic matter. However, the burning of fossil fuels is the largest source of carbon emissions.
