The series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

ANIMATION: Alveoli are the site of gaseous exchange in the lungs, where oxygen is taken up by the red blood cells and carbon dioxide is released for exhalation out of the body.

Cellular respiration is the process where energy that was stored in nutrients within the body is released. Both autotrophs and heterotrophs use cellular respiration. Glucose and oxygen are combined to create carbon dioxide, water, and energy. There are two different types of cellular respiration:  anaerobic and aerobic. When oxygen is neither required nor consumed it is anaerobic respiration. When oxygen is required and consumed it is aerobic restoration.

What is the 'other carbon dioxide problem'? How are humans driving changes in the chemistry of the ocean, and what might this mean for marine ecosystems in the future?
