The Oxygen-Carbon Dioxide Cycle

OXYGEN  Cells use oxygen to complete important jobs  All living things used oxygen  Cells die if do not receive oxygen  Important element needed by living things Product of photosynthesis

OXYGEN

Carbon Dioxide  Colorless and odorless gas  Raw materials for food making  Released when we breathe out  From burning fossil fuels

Carbon Dioxide

How are oxygen and carbon dioxide produced in plants and animals?  Through photosynthesis  Carbon dioxide combined in cells inside the plant

 Plants release oxygen as a waste product

EXCHANGE OF GASES  Plants give off oxygen  People and animals give off carbon dioxide  Continuous exchange of oxygen and carbon dioxide
