Intuitive fred888: My question on line was: "what do trees do with Carbon Dioxide"?

I have always known most of my life since I was old enough that Trees are symbiotic with human beings.

So, we breathe in the oxygen generated by Trees and things like plankton in the oceans of the world.

Without things like trees and plankton humans could not breathe the air here on earth.

So, humans have a symbiotic relationship (dependent upon each other for life) with trees and plants because of this. So, photosynthesis is the basis of life on earth to begin with. Photosynthesis creates oxygen from Carbon dioxide and then the trees and plants store the carbon in their trunks and limbs and twigs and leaves. Humans then breathe in the oxygen that is no longer carbon dioxide processed by trees and plants and this is how we are symbiotic with all trees and plants here on earth.

Trees draw carbon dioxide from the atmosphere through a process called photosynthesis. Plants use photosynthesis to produce various carbon-based sugars necessary for tree functioning and to make wood for growth. Every part of a tree stores carbon, from the trunks, branches, leaves, and roots.

Question

What role do trees and plants play in reducing carbon dioxide in the atmosphere?

Answer · 0 votes

Trees and plants stabilize and reduce the level of carbon dioxide in the air, mainly by the process of photosynthesis. Trees and plants act as carbon sinks. They do this by absorbing carbon dioxide in the atmosphere. This carbon dioxide is used by plants to synthesize food for themselves using sunlight as a source of energy and to release oxygen into the air. Furthermore, carbon dioxide accumulates in the plant in various forms such as stems, leaves, and roots. From plants, it is sent to the soil where the carbon is used as the main source of energy by soil-dwelling organisms and other plants. Therefore, in this way plants try to reduce the level of carbon dioxide in the atmosphere.

Question

Do trees emit more carbon dioxide than they absorb?

Answer · 1 vote

No. All plants use both photosynthesis (using light and carbon dioxide to make hydrocarbons/sugars) and respiration (using sugars and oxygen to make energy and carbon dioxide). As a tree grows, the hydrocarbons generated from photosynthesis are used to build the molecules that make up the tree (mainly cellulose). This essentially locks away the carbon dioxide until the tree dies and decays. Once a tree has finished growing, it's consumption of carbon dioxide and its generation of carbon dioxide will broadly be in balance (carbon neutral). Deforestation contributes to global warming as the carbon dioxide held in the trees is released as they decay and there are no growing trees to absorb it. Forests only remove carbon dioxide from the environment while they are expanding and only dump carbon dioxide into the environment when they are shrinking.

Question

What is the final destination of the CO2 captured by trees? Their bodies? If that, is it released back into the atmosphere if the woods happen to burn down?

Answer · 1084 votes

Some of it, yes. Photosynthesis converts energy from the sun and CO2 into glucose molecules (and oxygen). Some of this is stored as sugars and starch (simple polymers of sugars). Much of it goes into production of structural compounds like cellulose and lignin which make up much of the wood and leaves. However, approximately 65% of CO2 taken up by trees is returned to the atmosphere. Trees consume energy stores for growth and maintenance, a process called respiration. This is similar to respiration in our own bodies, and also requires uptake of oxygen. So during an average year, a tree only retains 35% of the carbon it initially collected, released through diffusion by roots and other tissues. When a forest burns, wood consumed by fire is reconverted to CO2. Yet much of the woody material remains unburnt, depending on the location, fire intensity, and tree species. This unburnt wood will begin to decay in time, a process that might take years to decades. Also, roots often remain unburn…

Question

Where do trees obtain carbon from?

Answer · 0 votes

The trees obtain Carbon from CO2 that comes from atmosphere Explanation: The trees get carbon from carbon dioxide which trees obsorb from atmosphere for the process of photosynthesis. The trees absorb CO2 from atmosphere from leaves, which had little openings called as stomata (more on lower surface of leaves). This CO2 is one of the main ingredient in photosynthesis, in which in presence of sunlight, water (absorbed from roots), carbon dioxide (from atmosphere) and chlorophyll (green pigment in leaves) forms glucose (C6H12O6).

Question

Which tree consumes most carbon dioxide and poisonous gases?

Answer · 29 votes

I was curious about which trees absorb the most CO2 and Googled for this a while back. I found that there are several websites that list trees that are good in absorbing carbon, e.g. this website and this website. Both sites list trees like: • Pine (Ponderosa, red, white and Hispaniolan pines) • Oake (Scarlet, Red and Virginia Live Oak) • Douglas fir • Bald Cypress • Common Horse-chestnut • Black Walnut • London Plane • American Sweetgum However, there is one site1 2 that has an entirely different list: • Trembesi a.k.a rain tree (Samanea saman) • Bamboo (Bambuseae) • Cassia (Cassia sp) • Cananga/Kenanga (Canangium odoratum) • Pingku (Dysoxylum excelsum) • Banyan/Beringin (Ficus benyamina) • Krey Payung (Fellicium decipiens) • Matoa (Pometia pinnata) • Mahogany (Swettiana mahagoni) • Saga (Adenanthera pavonina) As also mentioned by theUg and Blue_hat in their comments below, the first list probably applies to temperate climates, and the second one to tropical climates. Note that for…

Question

Do trees really get a large share of their mass from the carbon in the air?

Answer · 33 votes

The vast majority of a tree's carbon comes from the air, which averages 0.03-0.04% by volume (300-400 ppmv) CO2. This is fixed through photosynthesis and eventually stored as glucose which the plant can then use for its metabolism. Doing some quick math, this means that in order to produce 1 kilogram of carbohydrates (e.g. cellulose) a plant needs to process on the order of 2000-3000 cubic meters of air (and ≈550 g or mL of H2O), which would fill a cube measuring 13-14 meters on a side. Note this is an ideal figure; a plant's fixing efficiency will likely fall as it depletes the air of CO2. Plants do take a great deal from the ground, namely water, fixed nitrogen (for proteins), phosphorous (for nucleic acids), and several ions (sodium, potassium, calcium, among others)

Question

Trees taking carbon dioxide from the atmosphere where does the tree put the carbon atoms from carbon dioxide

Answer · 0 votes

Final answer: Trees absorb carbon dioxide during photosynthesis, storing carbon in their fibers and reducing atmospheric CO2 levels. Deforestation and burning fossil fuels release this carbon, contributing to climate change. Explanation: Trees have a critical role in taking carbon dioxide from the atmosphere and incorporating the carbon atoms into their structure. This is an essential process in the cycle of life on Earth and is part of what regulates our planet's climate. Through photosynthesis, trees convert carbon dioxide into glucose and oxygen. The carbon becomes part of the tree's mass, mainly within the structural fibers, such as cellulose, that make up the tree's trunk, branches, and leaves. As trees grow, they accumulate more carbon, effectively acting as a carbon sink and helping to mitigate climate change. Deforestation significantly impacts this process as it reduces the number of trees available to absorb carbon dioxide. Additionally, when trees are burned or decompose, th…

Question

How do internal structures of the tree function together to help a tree take in and lock up carbon atoms from carbon dioxide in the wood of the tree as it grows?

Answer · 85 votes

1. Photosynthesis: The process begins with photosynthesis, where the tree's leaves absorb sunlight and carbon dioxide (CO2) from the atmosphere. The chlorophyll in the leaves uses the sunlight's energy to convert CO2 and water (H2O) into glucose (a simple sugar) and oxygen (O2). The glucose is used as a source of energy and building material for the tree, while the oxygen is released back into the atmosphere.

Question

How does increased carbon dioxide in the atmosphere affect the growth of trees?

Answer · 0 votes

Increased carbon dioxide in the atmosphere can have varying effects on the growth of trees. Some studies suggest that faster tree growth does not necessarily lead to increased carbon storage, as carbon is inevitably released back into the atmosphere. However, other studies have shown that elevated carbon dioxide levels can act as a fertilizer, leading to higher photosynthesis and better growth responses in some tree species. Forest-Air-Carbon dioxide-Enrichment (FACE) studies predict a potential increase in tree productivity of 23-28% at least until 2050. Additionally, elevated carbon dioxide can induce partial closure of leaf stomata, resulting in reduced transpiration and more efficient water use by trees. However, it is important to note that the responses to increased carbon dioxide can vary among species, with some dominating the natural vegetation and potentially impacting biodiversity and ecosystem structure.
