carbon dioxide-oxygen cycle

The flow of carbon dioxide and oxygen through Earth's ecosystems


This relates to the relationship between CO₂-breathing plants and O₂ breathing lifeforms. All oxygen-breathing lifeforms take in oxygen and exhale CO₂. Plants take in the CO₂, use it in their photosynthesis process, and in turn give off ["exhale"] oxygen.

In this cycle trees and plants let off oxygen and take in carbon dioxide. All living animals need oxygen to live. When people cut down trees we are loosing more and more oxygen. The carbon dioxide produced in cellular resperation is used in the photosynthesis, this is the oxygen - carbon dioxide cycle. that is what happens duing the carbon dioxide - oxygen cycle.
