How much carbon dioxide do trees give off at night?
During the day, a tree will take in carbon dioxide to use in photosynthesis, and give off oxygen created in the process. At night, when there is no sunlight to power photosynthesis, trees get energy through cellular respiration, oxidizing some of their stored carbohydrates. Thus at night they take in oxygen and give off carbon dioxide.
Is it true that during the day plants take in carbon dioxide and give out oxygen but during the night plants take in oxygen and give out carbon dioxide?
At night they do. During the day, they give off oxygen. All normal plants, in the process of photosynthesis, take up carbon dioxide by day and release oxygen. This switches over in the dark, and they then produce carbon dioxide through respiration in the same way as animals. While they are growing, they take up more carbon dioxide overall than they give out, which gets turned into plant tissues (especially cellulose and, in the case…
Why do plants give out carbon dioxide in the dark and oxygen in the light and can this reduce oxygen in the bedroom at night?
It is said that by planting more trees will help in increase oxygen level but even they give out carbondioxide during night time so the quetion is why not the carbondioxide level increases by planting?
Trees are part of the carbon cycle, as is much of nature. Rotting trees release carbon dioxide, growing trees take it back out of he atmosphere, and in return, they give us oxygen in the photosynthetic cycle. If too many forests are destroyed, then this balance is disturbed, and levels of carbon dioxide increase.
carbon dioxide is needed for the trees. we need oxygen and they need carbon. we breathe out carbon dioxide and somehow i guess trees breathe out oxygen and then everyones happy!! answ2. Carbon dioxide is produced by volcanoes, and since the Algae invented photosynthesis, (about 2.4x109 years ago) we have had plants to suck up CO2 and give out O2. And grow lots of trees and grass and fruit. Which is a good idea.
Carbon Dioxide is exhaled by all living animals, even humans. The build up of Carbon Dioxide is poisonous but it's needed for this operation. Plant life, like trees, grass, flowers, etc., feed off of Carbon Dioxide, and they give off Oxygen. So what animals exhale, plants feed on and give us air in return.
