The Carbon Dioxide-Oxygen Cycle
The Flow Of Carbon Dioxide And Oxygen Through Earth’s Ecosystems
In the chloroplasts in plant cells, plants make sugars by combining Carbon dioxide from the air with water they absorb through their roots, in the presence of sunlight.
During photosynthesis Oxygen is produced as a by-product and released into the air as a gas.
Cellular Respiration In Animals
Within the mitochondria of animal cells, Oxygen combines with sugars to produce energy.
In this process Carbon dioxide is produced as a waste product and released into the air as a gas.
