No on the contrary it converts oxygen imto carbon dioxide, making it poisonous.
Oxygen
Yes oxygen enters the air during photosynthesis after the plant has produced sugar it releases oxygen
Combustion. It fits this pattern: fuel + oxygen --> carbon dioxide + water. It also releases heat.
Photosynthesis consumes carbon dioxide from the atmosphere, and releases oxygen.
The amount of oxygen released into the atmosphere has not noticeably increased in recent years. The amount of oxygen (O2) in the atmosphere is about 21%. It is part of the earth's oxygen cycle, the main driver of which is photosynthesis. Vegetation removes carbon dioxide (CO2) from the atmosphere, releases the oxygen (O2) and stores the carbon (C).
no it burns the oxygen and releases co2 (carbondioxide) among other pollutants
Carbon monoxide is produced during incomplete combustion of any hydrocarbon or fossil fuel. Adding oxygenates (molecules containing oxygen) to the fuel and maintaining the proper air/fuel ratio can reduce the amount of carbon monoxide generated.
Combustion. Fossil fuels contain carbon, hydrogen, Nitrogen, Oxygen and some other elements. But the largest is Carbon. So when such fuels burn they combine with the Oxygen and Nitrogen in air to form Carbon dioxide, Nitrogen oxides etc. Any form of carbon when burns produces carbon dioxide.
Oxygen
No. Most nitrogen oxides in the atmosphere are a product of combustion of some fossil fuel in air, when the heat of combustion is sufficient to activate reactions between atmospheric nitrogen and oxygen, but the oxides are not present in the fuel itself.
Hydrogen
Photosynthesis.
Combustion releases carbon dioxide as the carbon in the organic material is joined with oxygen from the atmosphere. Carbon dioxide is understood to be a greenhouse gas, meaning it traps heat in the atmosphere.
Photosynthesisplants: photosynthesis
plants do it by photosynthesis. And animals do it by respiration
The burning of fossil fuels are a combustion reaction. The reaction for the combustion has the reactants of propane (C3H8) and oxygen (O2). The combustion reactions products are carbon dioxide (CO2) and water (H2O).
"where the oxygen level increases then combustion takes place"
