Carbon dioxide can be added to the air by nature or by people and their activities.
Three Natural ways:
Three Man-made contributions:
A photoautotroph gets its energy initially from light, and its carbon from carbon dioxide.
When you breathe out, your body gets rid of Carbon Dioxide (CO2).
Methane burns in oxygen and gets oxidised. Carbon is oxidised to carbon dioxide, hydrogen to water.
Carbon dioxide is removed from cells by a process known as diffusion.
It gets the Carbon Dioxide form the air. It has holes in its leaves to set the air in called 'stomata'.
Autotroph
Carbon dioxide is expelled from our lungs.
A photoautotroph gets its energy initially from light, and its carbon from carbon dioxide.
When you breathe out, your body gets rid of Carbon Dioxide (CO2).

The more carbon dioxide the hotter the planet gets. The hotter the planet gets the more wild fires happen. For every fire that occurs more carbon dioxide is released.
Methane burns in oxygen and gets oxidised. Carbon is oxidised to carbon dioxide, hydrogen to water.
Oxygen is taken in by the body, carried by the blood to cells, where it is used for energy production. Carbon dioxide is produced as a waste product, then transported by the blood back to the lungs to be exhaled. This continuous process ensures that the body receives oxygen and gets rid of carbon dioxide efficiently.
