Answer :
Carbon dioxide or bicarbonate converts into organic molecules through photosynthesis of land plants, bacteria, and algae. Organic molecules made by those who use photosynthesis are then passed through the food chain and later through cellular respiration are converted back into carbon dioxide gas and released into the atmosphere. An example would be the slash and burn agriculture practices we are burning organic matter releases carbon into the atmosphere as CO2, CO, or carbon particulates.
A biological process whereby carbon is converted from organic molecules to a gas and then returned to the atmosphere can occur during cellular respiration.
- Respiration simply means when living organisms breathe in oxygen and then release back carbon dioxide to the atmosphere.
- Respiration is necessary for living organisms to produce energy. In this case, glucose is combined with oxygen from the air which are then changed into energy and carbon dioxide during respiration.
In conclusion, during respiration, carbon is turned into gas and then returned to the atmosphere.
