Carbon dioxide from the air gets taken in by plants who use photosynthesis to create sugars and starches which are then consumed by animals. The animals then inhale oxygen and exhale CO2
(Respiration; breathing) back in the air and eventually they die
and their body turns into fossil fuel over time. Industries take
the fossil fuels and sell it to people as oil or gas. The gas is
burned producing CO2 that is also put back into the air. This cycle
starts all over again
Carbon cycle is a series of processes that involve incorporation of carbon dioxide into living tissues by photosynthesis, and its return to the atmosphere via respiration.
