A 100-ft tree, 18 diameter at its base, produces 6,000 pounds of oxygen.. - Northwest Territories Forest Management. - Environment Canada, Canada's national environmental agency. On average, one tree produces nearly 260 pounds of oxygen each year.
Most of this oxygen comes from tiny ocean plants â called phytoplankton â that live near the waterâs surface and drift with the currents. Like all plants, they photosynthesize â that is, they use sunlight and carbon dioxide to make food. A byproduct of photosynthesis is oxygen. Scientists believe that phytoplankton contribute between 50 to 85 percent of the oxygen in Earthâs atmosphere. They arenât sure because itâs a tough thing to calculate. In the lab, scientists can determine how much oxygen is produced by a single phytoplankton cell. The hard part is figuring out the total number of these microscopic plants throughout Earthâs oceans.
