How do trees absorb carbon?

Trees absorb carbon through photosynthesis.

6CO2+12H2O+Energy=>C6H12O6+6O2+6H2O

So basically trees take in co2, water and energy from the sun and use it to make glucose, oxygen, and water.

When trees die, they carbon dioxide they stored goes back into the atmosphere as the tree decomposes.

Do Trees Absorb Carbon Dioxide

First of all, they absorb CO2 a lot more than half the time otherwise all the O2 in the world would have long since disappeared. I believe they do this about eighty percent of the time and they respirate about twenty percent of the time. This accounts for how they absorb and store carbon.

And to all the previous answerers (I'm sure I'll get negative marks for this but I feel I should probably educate you) trees don't store carbon dioxide. If you look at your own equations you will see this. They turn it into glucose. THEY STORE GLUCOSE. Not carbon dioxide. Carbon dioxide is not released when trees die. The only thing that releases carbon dioxide on a dead tree are the living microorganisms that decompose the tree.

I definitely would not pay you 65 Euro per year per tree. But I would support a tax structure that did not charge a land tax for undeveloped land. Nobody seems to realize that a forest isn't just trees. In Nova Scotia the Flying Squirrel is endangered. There is a complex relationship among the squirrel, the tree, fungi and insects. Without all the creatures in the chain, that ecosystem will eventually fail. It doesn't really matter what you plant, if you are going to use pesticides and create acreage which is only suitable to grow trees which were never indigenous at the cost of all the creatures which make up the plant / animal food chains, you never will return it to it's natural state. Human design doesn't even come close to the complexity of natural design. But if you can make 65E/yr/tree ... I'm giving up my job and going planting trees.

How do trees absorb carbon?

trees absorb co2 and give off oxgen half of the time and then reverse the process the other half of the time so how do they absorb and store carbon?

The pores are called stomata.

Stomata are tiny plant structures found on the outer skin layer, also known as the epidermis, of plants. They consist of two specialized cells, called guard cells that surround a tiny pore called a stoma. The word stomata means "mouth" in Greek because they allow communication between the internal and external environments of the plant. Their main function is to allow gases such as carbon dioxide, water vapor and oxygen to move rapidly into and out of the leaf. Stomata are found on all above-ground parts of plants including the petals of flowers, petioles, soft herbaceous stems and leaves. They are formed during the initial stages of the development of these various plant organs and therefore reflect the environmental conditions under which they grew.

simple...think....in the fall they die...so they release carbon dioxide...and in the spring they grow..so they absorb carbon dioxide....

they have small openings in the bottom of the leaves. they are called pores!
