You realize that asking the same question 3 times is not going to change the right answer. It is still the CO2 of the air.

In Photosynthesis, plants use the sun's energy as light to transform carbon dioxide and water into glucose.  In cellular respiration,  glucose is ultimately broken down to yield carbon dioxide and water, and the energy from this process is stored as ATP molecules.

Photosynthesis (photo=light, synthesis=putting together), generally, is the synthesis of sugar from light, carbon dioxide and water, with oxygen as a waste product. It is arguably the most important biochemical pathway known; nearly all life depends on it. It is an extremely complex process, comprised of many coordinated biochemical reactions. It occurs in higher plants, algae, some bacteria, and some protists, organisms collectively referred to as photoautotrophs.

The calvin cycle is the dark (non-light-requiring) biochemical pathway in plants that produces sugar from CO2.  It's discussed here: http://www.bio.umass.edu/biology/conn.river/calvin.html\n\nThe light reaction is also in chlorophyl, and uses the energy of light (photons) to start electron transport to generate energy in the form of ATP.  This ATP is then used by other processes including the dark reaction.  \n\nNote that the light reaction in plants is basically the same thing that goes on in mitocondria of eukaryotes (including plants), in which electron transport produces energy via ATP.  The dark cycle is essentially the reverse of glycolysis.  In the dark cycle sugar is produced at the expense of energy.  In glycolysis, sugar is broken down and energy released.  Glycolysis occurs in prokaryotes and eukaryotes (basially all living things), while the dark cycle only occurs in plants.

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy, CO2, and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis. \n\nPhotosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well!\n\nWe can write the overall reaction of this process as: \n\n6H2O + 6CO2 ----------> C6H12O6+ 6O2\nMost of us don't speak chemicalese, so the above chemical equation translates as:\n\nsix molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen\n\n\nDiagram of a typical plant, showing the inputs and outputs of the photosynthetic process.

A leaf may be viewed as a solar collector crammed full of photosynthetic cells.\n\nThe raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.\n\n\nCross section of a leaf, showing the anatomical features important to the study of photosynthesis: stoma, guard cell, mesophyll cells, and vein. Image from Purves et al., Life: The Science of Biology, 4th Edition, by Sinauer Associates (www.sinauer.com) and WH Freeman (www.whfreeman.com), used with permission.\n\nWater enters the root and is transported up to the leaves through specialized plant cells known as xylem (pronounces zigh-lem). Land plants must guard against drying out (desiccation) and so have evolved specialized structures known as stomata to allow gas to enter and leave the leaf. Carbon dioxide cannot pass through the protective waxy layer covering the leaf (cuticle), but it can enter the leaf through an opening (the stoma; plural = stomata; Greek for hole) flanked by two guard cells. Likewise, oxygen produced during photosynthesis can only pass out of the leaf through the opened stomata. Unfortunately for the plant, while these gases are moving between the inside and outside of the leaf, a great deal water is also lost. Cottonwood trees, for example, will lose 100 gallons of water per hour during hot desert days. Carbon dioxide enters single-celled and aquatic autotrophs through no specialized structures.\nVirtually all oxygen in the atmosphere is thought to have been generated through the process of photosynthesis. Obviously, all respiring organisms (including plants) utilize this oxygen and produce CO2. Thus, photosynthesis and respiration are interlinked, with each process depending on the products of the other. The global amount of photosynthesis is on the order of a trillion kg of dry organic matter produced per day, and respiratory processes convert about the same amount of organic matter to CO2. A large part (probably the majority) of photosynthetic productivity occurs in open oceans, mostly by oxygenic prokaryotes. Without photosynthesis, the oxygen in the atmosphere would be depleted within several thousand years. It should be emphasized that plants respire just like any other higher organism, and that during the day this respiration is masked by a higher rate of photosynthesis.

This time we use oxygen to burn the sugar:\n\nSugar + Oxygen = Carbon Dioxide + Water + Energy\n\nUsing glucose:\nC_6H_12O_6 + 6 O_2 -> 6 CO_2 + 6H_2O + Energy

i think it does, where does the carbon in the trees come from otherwise? it comes from the carbon dioxide they use in photosynthesis\n\n--\nWell not indefinitely. If you burn the trees the carbon is released again, or if they decompose the carbon is released as carbon dioxide. I think its called the carbon cycle.

It is grabbed from the CO2 in the air.  Protosynthesis involves combining carbon dioxyde from the air with water to produce sugars and release oxygen.

Yes, they can. \nHumans produce carbon dioxide (CO2) through respiration: \nC6H12O6 + 6O2 --> 6CO2 + 6H20\nPlants then use the carbon dioxide in photosynthesis:\n6CO2 + 6H2O --> C6H12O6 + 6O2\n\nNote that C6H12O6 is glucose. \n\nHope that helps! =)

A tree grows by photosynthesis: it combines carbon dioxide from the air with water, which it takes in through its roots, to produce glucose, which is converted into starch to be stored in the leaves. Minerals are also taken in through the roots which combine with glucose to produce amino acids, proteins and other stuffs that the tree needs e.g. phosphorus for DNA in the cell nucleus.\n\nThe equation for photosynthesis is:\n\n6CO2 + 6H2O -> C6H12O6 + 6O2\n\nWith research you should be able to find other equations for processes going on inside the tree.\n\nI have not described the first stages of the tree's life, i.e. germination. The increase in mass here is due to the uptake of water.

Photosynthesis uses the energy of light to make the sugar, glucose. A simple general equation for photosynthesis follows.\n\n6 CO2 + 12 H2O + light → C6H12O6 + 6 O2 + 6 H2O\nCarbon Dioxide + Water + Light energy → Glucose + Oxygen + Water\nPhotosynthesis occurs in two stages. In the first phase light-dependent reactions or photosynthetic reactions (also called the Light reactions) capture the energy of light and use it to make high-energy molecules. During the second phase, the light-independent reactions (also called the Calvin-Benson Cycle, and formerly known as the Dark Reactions) use the high-energy molecules to capture carbon dioxide (CO2) and make the precursors of glucose.\n\nIn the light-dependent reactions the pigment chlorophyll absorbs light and loses an electron that travels down an electron transport chain producing the high energy molecules NADPH and ATP. The chlorophyll molecule regains its electron by taking one from water, a process that releases oxygen gas.\n\nIn the Light-independent or dark reactions the enzyme RuBisCO captures CO2 from the atmosphere and in a complex process called the Calvin-Benson cycle releases 3-carbon sugars which are later combined to form glucose.\n\nPhotosynthesis may simply be defined as the conversion of light energy into chemical energy by living organisms. It is affected by its surroundings and the rate of photosynthesis is affected by the concentration of carbon dioxide, light intensity and the temperature.

Carbohydrates are formed when plant completes both light and dark reaction.\n\nIn light reaction when ADP molecules get energy they are converted into ATP.Water breaks into and H+ and OH-.H+ reduces NADP(nicotinamine adenine dinucleotide phpospate) into NADPH2\n\nIn dark reaction there is a cycle of reaction called Kalvin-Benson cycle.The whole reaction can be given as follow:\n\n6CO2+12RuBp + 12NADPH2 + 18ATP------------C6H12O6+12RuBP + 12NaDP +6H2o + 18ADP
