Yes. Leaves become less efficient as they age and the plant kills them off. Most obviously, a deciduous tree will also kill and shed its leaves in the autumn when the reduced light means that it is no longer worthwhile to keep them alive.
There is a lot of variation between plants.
Yes, because when people drive their cars and do alot of polluting things, it goes in the air and goes into the leaves.
no
The photosynthesis of plants. Respiration of any type released carbon dioxide.
when any organism with lungs breathes in...then out.
The amount of carbon dioxide emitted each year varies according to the amount of forest burnt. However, there is no net increase in atmospheric carbon dioxide from forest fires, as long as the forests are allowed to recover and regrow.AnswerVery little, compared to human emissions. It's hard to say exactly... It is 25.687%, approximately, it is 25.7%it is 25.687%
Any burning process release carbon dioxide.
When Carbon or any other organic compound udergoes combustion, carbon dioxide is produced alongwith a release of large amount of energy as heat. C + O2 = CO2
Grass absorbs carbon dioxide just like any other plant. from under it's leaves. The funny part about that is that the grass itself (aside from it's roots) is the leaf!
Any fossil fuels, hydrocarbons like coal, oil and natural gas, release carbon dioxide and water when burned.
Most active volcanoes release sulfur dioxide and carbon dioxide into the atmosphere, which is air pollution
Carbon dioxide Carbon dioxide remove oxygen by any means
There are many activities which release Carbon into the air. Some of these include the breathing [metabolism] of living animals, the burning [oxidation-reduction] of Carbon containing compounds found throughout living things in nature, and some chemical reactions of carbon containg compounds in rock and soil.
Carbon dioxide levels influence how many sugars(glucose) a plant can produce greatly. This is because 6 molecules of water and 6 molecules of carbon dioxide will release a sugar through series of reactions. So if you have many carbon dioxide molecules it makes it a lot easier for a plant or any other photoautotroph.
It is possible to breathe in carbon dioxide because if you smoke, you will breathe in carbon dioxide.
