animals and people breath out carbon dioxide and plants use carbon dioxide
Carbon dioxide is a waste product breathed out by living animals. Excessive intake of carbon dioxide can lead to carbon dioxide poisoning.
People are adding carbon dioxide to the atmosphere by burning fossil fuels. I believe
Both. Cars emit Hydrocarbons + Nitrogen Oxides + Carbon Dioxide + Carbon Monoxide. People emit Methane and Carbon Dioxide.
No it won 't. Carbon dioxide is from the trees. If people cut down trees we won't have carbon dioxide.
Carbon Dioxide?
no not necessarily.
Carbon Dioxide.
No, it is the other way round, people breath in Oxygen (O2) and breath out Carbon Dioxide (CO2).
Because people burn things (fuel, wood, coal, etc) and there are more people than ever before.
Plants are unique in that they make their own food, but they require certain things to make that food. Water is a plant's major source of nourishment, but what is equally important to plants is carbon, or carbon dioxide. They use carbon dioxide to help promote growth and discard the oxygen for people to breathe.
nitrogen oxygen and carbon dioxide are important into the plants because without them there are no plants in the world and people will die cause there is no carbon dioxide
