4.9 CARBON CYCLE

photosynthesis= CO2 +H20--> C6H1206 +02
carbon dioxide comes from the atmosphere,
photosynthesis occurs to reduce the co2 in the atmosphere

feeding= producer--> primary consumer --> secondary consumer
each stage carries around the process such as respiration. respiration add co2 to the the atmosphere

decomposition
death of the organism, the organic molecules ----> ( bacteria fungi)--> co2

combustion
fossil fuels--(oils coals)---> co2
= industrial/vehicles
