Where does the carbon dioxide in breath come from? what organisms use carbon dioxide to survive? research the amount of carbon dioxide generally found in the air and in breath. which has more carbon dioxide? what are some of the other sources of carbon dioxide in air? based on your observations about the acidity of carbon dioxide dissolved in water, what ecological effects could be caused by excess carbon dioxide in the air?

Answer 1:

The carbon dioxide in the breathed out air is a by-product of the process of cell respiration. In respiration, a molecule of carbohydrate is converted into a CO2, H20, and energy which is released in form of ATP.

Answer 2:

All plants belonging to kingdom Plantae and plant-like organism like photosynthesizing bacteria need CO2 to survive. They use carbon dioxide in food making process, photosynthesis.

Answer 3:Amount of CO2 in the air: 0.03%Amount of CO2 in the breath: 4%

Hence it is proved from above statistics that breath has more carbon dioxide than air.

Answer 4:

There are two sources of CO2 in the air. Which are the following:

Human sources: It includes activities of human involvement and release of CO2 artificially as in cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.Natural sources: Release of CO2 by natural processes as in decomposition, ocean release and respiration.Answer 5:The major ecological effect is global warming.As CO2 is known as the greenhouse gas because it gives a greenhouse effect. Elevating concentration of CO2 in air forms a layer or sheath of CO2 over the earth which allows the entry of sun rays and stop it from reflecting back, trapping sun rays around earth increasing the temperature of earth day by day. It also causes plants to provide less evaporative cooling because in high concentration CO2 stomata shrink through which normally evaporation occurs when stomata are open.
