Carbon Cycle

SC.8.L.18.3

Which chemical processes produce and release carbon dioxide into the atmosphere?

• Autotrophic plants using photosynthesis in the chloroplast to produce glucose

• Combustion (burning) of fossil fuels for electricity and transportation

• Autotrophic plants and heterotrophic animals that use respiration in the mitochondria to produce ATP energy

• Heterotrophic decomposers that use decaying and dead material in the ground for energy
