1) Take a piece of wood, fruit seed or some feathers and heat it. Observation: Slowly the color changes to black. Upon getting charred they all turn black.

Therefore we can conclude that all plant and animal products contain carbon.

2) Hold lighted candle in a gas jar. Observation: The gas jar gets filled with CO2 and extinguishes the burning candle that suggests that C02 neither burns nor does it support burning.
