the amount of CO2 inhaled by a plant during the day & exhaled during the night?

Plants don't exhale CO2.  They exhale O2 which is what we inhale.  We exhale CO2.\nScience calls that "symbiosis".  I call it a very good reason to have green plants around!\nAs far as the amount, you'll need to provide more specific data - such as how big the plant is, for starters.

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

No photosynthesis. There is a time of course where plants do not photosynthesize. It is normal. But if you are talking prolonged states of no photosynthesis in all plant biomass, the amount of carbondioxide would go up and 1/since there will be a deficieny in oxygen life on earth would be at risk 2/since CO2 is a green house gas, global warming will be accelerated

The lungs excrete carbon dioxide (a waste product from metabolism)

CO2 + H2O + light = C6H12O6 + O2

When a plant (a collection of cells) metabolizes and goes through its respiration, it requires carbon dioxide. It gives off oxygen as a by-product.\n\nWhen an animal (a collection of cells also) metabolizes and goes through respiration, it requires oxygen and gives off carbon dioxide.

the answer is CARBON DIOXIDE

weel it depends. humans produse carbon dioxide for oxygen taken into the body. The human Co2 productivity in relevance to the atmosphere is somehow conciderate. We expell the gas ( Co2 ) which makes us part of the contributing factor to its presence. Our surface area to volume ratio limmit us the dirrect impact to the Co2 we produse as a result of respiration.

CO2 is moved into cells that are not respiring, so that when the stomata are closed, the plant has CO2 available for respiration, and O2 is not lost from the stomata being open.  C4 plants are found in hot and dry environments where losing O2 would be a disadvantage

Plants don't inhale oxygen, they "inhale" carbon dioxide and release it to make oxygen.

Carbon dioxide from air, water & minerals from soil.\n\nA simple answer for a complex process!

Every time you exhale, you breathe out most of the air you breathed in. While the air is in your lungs, oxygen travels from air to blood and CO2 from blood to air, in each case moving naturally to where it is less concentrated.\n\nHow long it takes the average oxygen molecule from being absorbed to being breathed out again as part of a carbon dioxide molecule is a really good question - I have no idea if anyone has even calculated it, but we can try.\n\nMost people pass out if their blood oxygen level drops below about 80% - and most people can hold their breath for maybe 4-5 minutes (the record is almost 9 minutes by Houdini, but that's someone trained and a bit freakish). That implies you use 20% of the oxygen in, say, 5 minutes - so it would take 25 minutes to use it all, if that were physically possible.\n\nBTW, I'm prettty sure it's 8-9 pints of blood. The normal O2 reading in arterial blood is around 10-13 kPa, but I'd have to admit I don't know how to convert that to a mass (or free volume) of oxygen.\n----\nOoh, here you go: arterial blood contains about 20ml of oxygen per 100cc. Your blood volume is about 5 litres, so that would mean your body contains rather less than a litre of oxygen (because not all of your blood is fully oxygenated).
