yes they do (i think)
not really sure HA you were hoping to get a proper answer!
Animals produce co2 and plants produce o2 and co2
Any ethanol producing fermentation makes CO2, so it's not a matter of can, it will produce CO2.
Steam trains were first. they use both fire and water to produce steam and make the engine run.
Because dry seeds have a very low metabolic rate and do not produce much Co2. Germinating seeds produce more Co2.
CO2?
CO2
carbon, oxygen
no, not at all. albeit amount of released oxygen can reach lower or even lowest but can't produce CO2.
Trains are better for the environment - as they produce less pollution per passenger than cars do.
Mulch itself does not produce CO2. Instead, when organic mulch decomposes, it releases small amounts of CO2 as a byproduct of the natural decomposition process. The amount of CO2 released will depend on factors such as the type of mulch, its thickness, and environmental conditions.
