Plants use co2 as a way to produce a special sugar that they eat. They only use the carbon and realise the remaining oxygen (o2).
because plants breathe in carbondioxide and breathe out oxygen which animals and human breathe in if there is no carbondioxide there will be no plants ,no animalsand no humans which means no life on earth.

carbondioxide.
the process in the green plants in certain other organisms by which carbohydrates are synthesised from carbondioxide and water using light as an energy source
Methane and carbondioxide.
carbondioxide
They breath it in and give out oxygen.
for new plants,oxygen,and carbondioxide.
Plants produce Oxygen and Carbondioxide so the plants have to made out of energy
plants give us oxygen and take carbondioxide
Producers are green plants. And these plants are green because of a pigment called 'Chlorophyll'. This pigment with the help of carbondioxide from air and sunlight creates food for the plant by a process call 'Photosynthesis'. All other living things in the food chain survive because of this natural ability (Photosynthesis) of plants.
