Which tree absorbs more CO2?

Answer 1

Deciduous trees are generally thought to inhale more carbon dioxide than other trees. It's because deciduous are usually broad leaved, so they are more efficient in photosynthesis. Here is a list of some trees that take in a lot of carbon dioxide: English Oak

Common Lime

Horse Chestnut

Common Alder

Answer 2

Young, rapidly-growing plants (like row crops) absorb the most carbon dioxide per acre. Mature forests absorb the least. Especially if those mature forests are unmanaged, in which case the dead, rotting trees release enough carbon dioxide to nullify the little bit that the old living trees are absorbing.

A:Young, fast growing plants remove more carbon dioxide than do trees, but also produce more carbon dioxide when they die, giving no nett gain in atmospheric oxygen. Trees, on the other hand, retain their carbon dioxide, sometimes for centuries.

Best of all are natural forests, which can sequester carbon for thousands of years and assist in minimising global warming. Although individual trees die eventually, they are always replaced by new trees that absorb as much carbon dioxide as the trees they replace.

Answer 3

Quick growing species (e.g. poplar) absorb carbon dioxide more rapidly to support their growth rate. However at the end of the day the total kg CO2/kg Dry Wood is about the same for all trees.

Answer 4

While grasses may grow quickly and thereby absorb carbon dioxide more quickly than trees, what is more important in a greenhouse and global warming context is how much carbon is retained over a long period. This in turn depends on the mass and longevity of the plant. Clearly trees store far more carbon than grass. However even trees have no long term benefit if they are eventually harvested.

Answer 5

On average, younger trees tend to absorb more CO2 than older trees because they are in their rapid growth phase. However, in the long term, older trees have larger mass and volume, so they can store more carbon even though they absorb it at a slower rate. The overall impact on CO2 absorption depends on the age, species, and health of the tree.

Answer 6

I'm not sure I would characterize it as absorption but carbon dioxide enters a leaf through stomata on the underside of the leafs surface.

Answer 7

Usually the type of plant doesn't matter as much for things like transpiration and that, usually the weather conditions and other factors matter more.

Answer 8

I guess it is Oscimum sanctum[tulsi]

The oceans actually absorb most of the CO2. Over 70% of all CO2 absorption is by the oceans.
