Is carbon dioxide released when forests are cut down?
well when a tree is alive and is doing photosynthesis it stores up carbon dioxide and it releases oxygen. when the tree is cut down any remaining oxygen escapes and the stored up carbon dioxide is released which then contributes to the green house effect but in general cutting down trees is bad for the environment destroys habitats and adds to the greenhouse effect. in return we get paper and wood. if we keep cutting down trees and there is still a demand for paper and wood in our growing population rainforests and woods won't exist anymore and many many undiscovered species and animals will be lost and die out for ever.
Is that true about trees turn carbon dioxide into oxygen?
Yes. Trees take in carbon dioxide and water. Using sunlight they turn this into carbon, oxygen and sugar. They store the carbon and release the oxygen. This is called photosynthesis.
Whats the definition of gas released when trees are burned?
The gas released when trees are burned is carbon dioxide, a greenhouse gas that contributes to climate change. It is released as a byproduct of the combustion process, where the carbon stored in the tree is oxidized and released into the atmosphere.
How is carbon dioxide consumed on earth?
The earth's carbon cycle moves carbon dioxide in and out of the atmosphere, into oceans, soil, animals and vegetation and back again. The oceans absorb some CO2, but only the surface water. The oceans are becoming more acidic and damaging coral and fish. Trees and vegetation take in carbon dioxide and release oxygen. This carbon is stored within the plant or tree and stays there until the tree is destroyed. About half the weight of a tree is carbon.
Where does the stuff the tree is made of come from?
About half the body weight of a tree is carbon. The tree absorbs carbon dioxide from the atmosphere, stores the carbon, and releases the oxygen. As the tree grows, it stores more and more carbon.
How long is carbon stored in a tree?
Trees remove carbon dioxide from the air releasing the oxygen and retaining the carbon as sugar and cellulose. The cellulose is used to form wood and leaves. The sugar fuels the trees cellular growth and seed formation. The carbon is stored as wood (in the tree itaelf) and in the fallen leaves as humus or carbon in the soil.
What form does carbon take inside a tree?
Carbon inside a tree is primarily in the form of cellulose, which is a complex carbohydrate made up of repeating glucose units. Carbon is also stored in the form of lignin, which provides structural support to the tree's cell walls. Additionally, carbon can be found in sugars, starches, and fats stored in different parts of the tree.
Why is it important for humans to make sure that they don't cut down too many trees?
Because trees remove carbon dioxide, a powerful greenhouse gas, from the atmosphere. Through photosynthesis the oxygen is released and the carbon is stored in the roots, trunk and branches of the tree. 50% of a tree's weight is carbon.
How many pounds of carbon dioxide is remove form the atmosphere annually when a tree is removed?
When a tree is removed, it can release the carbon dioxide it has stored over its lifetime back into the atmosphere, instead of removing it. So, the removal of a tree can actually lead to an increase in carbon dioxide in the atmosphere, depending on how the tree is handled and if it is replaced with new plantings.
If a tree is cut down how might it release its carbon back into the atmosphere?
We are cutting down forests (deforestation). This is making the problem worse because the trees take up the carbon dioxide (during photosynthesis). when the tree dies, they release carbon dioxide back to the atmosphere. This answer is from an AQA revision book science A. QUESTION ANSWERS BY UWAYS KHALIFA
What is the Energy transformation for a tree?
A tree converts sunlight, water, and carbon dioxide through photosynthesis into chemical energy stored in glucose. This energy is then used by the tree for growth, reproduction, and other metabolic processes. Additionally, trees release energy in the form of heat during respiration, where glucose is broken down to release energy for cellular functions.
What geological process returns carbon to the atmosphere in the form of carbon dioxide?
Carbon never leaves our environment. Where is exists has always been the issue. Carbon makes up all living matter. This carbon is released into the ground or our air when the organism dies and decays or is burnt. A tree that is burnt will release the same amount of carbon as a tree that rots.
Is carbon dioxide released when forests are cut down?

How much carbon release from burning a tree?
Burning a tree releases approximately 50% of its carbon content back into the atmosphere as carbon dioxide. On average, a mature tree can store about 48 pounds (approximately 22 kilograms) of carbon per year, translating to around 1 ton (about 900 kilograms) over its lifetime. Therefore, when a tree is burned, it can release a significant amount of carbon dioxide, contributing to greenhouse gas emissions and climate change. The exact amount varies depending on the tree species, size, and moisture content.
What kind of gas increases un the atmosphere if a tree is cut down?
carbon dioxide
What happens to oxygen and carbon dioxide when you cut down?
well when a tree is alive and is doing photosynthesis it stores up carbon dioxide and it releases oxygen. when the tree is cut down any remaining oxygen escapes and the stored up carbon dioxide is released which then contributes to the green house effect but in general cutting down trees is bad for the environment destroys habitats and adds to the greenhouse effect. in return we get paper and wood. if we keep cutting down trees and there is still a demand for paper and wood in our growing population rainforests and woods won't exist anymore and many many undiscovered species and animals will be lost and die out for ever.
Explain where the carbon stored in fossil fuels comes from?
The carbon stored in fossil fuels comes from plants and algae that lived millions of years ago. These organisms absorbed carbon dioxide from the atmosphere during photosynthesis and stored the carbon in their tissues. Over time, the remains of these organisms were buried and under pressure and heat, transformed into fossil fuels like coal, oil, and natural gas.
