Like the person said above.  0.038% of the atmosphere is made up of CO2.  That's 3.8 parts per million.  So that's why it won't take very much for people to double the amount of CO2 that is naturally occuring.

at least one per year :)

People use the oxygen from the air and produce carbon dioxide. Trees use carbon dioxide and product oxygen. Trees also prevent erosion, provide many food products, provide shade and create an aestetically pleasing environment.

The process by which plants convert water and carbon dioxide into carbohydrates, using sunlight as the source of energy and the aid of chlorophyll.\n\nmethods of measuring rate of photosynthesis:\n\n1) Measure the uptake of CO2\n\n2) Measure the production of O2\n\n3) Measure the production of carbohydrates\n\n4) Measure increase in dry mass \n\nThe only one which won't work is to measure the uptake of water!\n\nUptake of CO2 can be measured with the means of an IRGA (Infra-Red Gas Analyser) which can compare the CO2 concentration in gas passing into a chamber surrounding a leaf/plant and the CO2 leaving the chamber\n\nCO2 uptake can also be measured by following the uptake of carbon dioxide labelled with 14C\n\nOxygen can be measured by a) counting bubbles evolved from pond weed b) with the Audus apparatus\n\nThe rate of decolourisation of DCPIP in the Hill Reaction is a measure of the rate of the light-requiring stages of photosynthesis\n\nThe production of carbohydrates can be measured crudely by monitoring the dry mass of a disc cut out from one side of leaf (with a cork borer) and compared with the dry mass of a similar disc cut from the other side some weeks later.\n\nDry mass is often monitored by the technique of 'serial harvests' where several plants are harvested, dried to constant weight and weighed - this is repeated over the duration of the experiment. \n\nAs the equation for respiration is almost the reverse of the one for photosynthesis, you will need to think whether these methods measure photosynthesis .\n\nI belive this information will be usefull for you.\nAll the best

For most trees it is between 5 - 10 years.

probably carbon dioxide mostly

Place a 2 in front of the HCl to balance the equation. Then you can see that for one mole of calcium carbonate, you get 1 mole of carbon dioxide.

In photosynthesis, plants convert light into chemical energy. This energy is thus used to turn carbon dioxide into carbohydrate releasing oxygen as a byproduct. That is why many plans to fix global warming such as the Kyoto Protocol aim to increase the number of forested areas through so-called carbon sinks.

rice,wheat,potato,etc...r some of the C-3 plants.....when they r exposed to co2(14),they produce 3C compound called phosphoglyceric acid.....this occurs only in mesophyll cells at an optimum temp of 20-25 degree C. Here photorespiration rate is high & leads to loss of fixed CO2. It also decreases CO2 fixation rate....

Your approch is right except, as said above you didn't take emmision of room in account. Every body which radiates, absorbs too. u must take that into  account.\n\nI got the similar answer around 263 K

Because the biomass of a rainforest is not really increasing, it is more at a steady state (or decreasing if you look at the amount of forest getting chopped down). \n\nPlants remove carbon out of the air. If they use it to grow, the carbon stays with the plant and is consequently removed from the atmosphere. If they use it for energy they convert it into carbondioxide again just like we do. In addition there are many decay processes in a rainforest (all releasing carbondioxide which had been fixed in plants). So as long as the mass of the rainforest stays about constant it won't really remove carbon dioxide from the air. \nIt's the same than first growing a field of some plant (which fixes carbon) and then burning (or eating) it (releasing the carbon) on average that's a carbon neutral act. \nIf we would let rainforest regrow on a lot of deforested land, that would remove carbondioxide from the atmosphere while the forest is growing in mass.

It is carbon dioxide molecules produced devided by oxygen molecules consumed. In humans it is roughly 0.8

trees dont breathe as such during the winter months, they go into a sort of no growth regime. That is why they have defined growth rings. They start 'breathing' carbon dioxide again in spring when the new growth cycle starts up again
