THE OXYGEN-CARBON DIOXIDE CYCLE.
Bellwork Name one thing you already know about oxygen. Name one thing you already know about carbon dioxide.
In: How is water related to oxygen?
Oxygen-Carbon Dioxide Cycle Both are GASSES important to all living things. Unlike water which always stays water, oxygen (O2) and carbon dioxide (CO2) convert back and forth as they cycle on the planet.
ANIMAL CONTRIBUTION During respiration (breathing), animals inhale oxygen (O2) and convert it to carbon dioxide (CO2).
PLANT CONTRIBUTION During photosynthesis (the process where plants make food for themselves) plants breathe in carbon dioxide (CO2) and exhale oxygen (O2).
DECOMPOSERS Dead organic material contains carbon dioxide (CO2), so as decomposers break down the tissue, carbon dioxide is released into the atmosphere.
FOSSIL FUELS Oil, Gas, Coal are examples. When these fuels are burned, they release carbon dioxide (CO2) and water (H2O) into the atmosphere.
