it comes from carbon oxidizing through fire.
It also comes from a lot of other places. Carbon dioxide is a waste product of cellular respiration. It diffuses into the blood from the cells and travels to the lung where it is exhaled into the air.
carbon dioxide is a air which comes from the plants
When you exhale, carbon dioxide comes out of your lungs.
The carbon to produce carbohydrates in the second stage of photosynthesis comes from carbon dioxide in the atmosphere. During the Calvin cycle, carbon dioxide is fixed and converted into glucose molecules that make up carbohydrates.
The carbon dioxide slowly comes out of it.

Carbon Dioxide, Water and protein.
For most terrestrial plants, nearly all the carbon comes from carbon dioxide in the atmosphere. For aquatic plants, the carbon comes form carbon dioxide dissolved in the water.
it comes from the body

The carbon in plants come from the carbon found in carbon dioxide (CO2). As plants undergo photosynthesis they draw in water through their roots and carbon dioxide from the air through specialized structures called stomates. So the inorganic carbon in carbon dioxide becomes organic carbon making up the oils, carbohydrates and proteins found in plants.
The carbon dioxide you exhale comes from the food you eat, which is broken down in your body to produce energy. This process releases carbon dioxide as a waste product that is then exhaled when you breathe out.
