Because when we breath out we let out carbon dioxide and when we breath in we take in oxygen because we cant breath in carbon dioxide . Trees are living just like us so but they breath in carbon dioxide and breath out oxygen so without trees we would'nt be here . also they make great furniture
Trees take in Carbon Dioxide and release Oxygen. We as humans breathe in this Oxygen.
Foetus never breath, it only start after delivery
Well trees don't breathe, but they take in carbon dioxide and release oxygen.
dong improved: ( i don't know what dong means) sorry! anyway, the job of plants, like trees, is to give oxygen out of there plant bodies. they take in our carbon dyoxide, that we breath out and then they "breath" in the carben dyoxide we breath out then they "breath out oxygen. oxygen is in the air we breath. we have to have oxygen to live and breath. GOD made the plants and trees that way so we could live. without GOD we wouln't be here. :)
Between 1 second and 100 years, don't hold your Breath...
Trees take carbon dioxide and turn it into oxygen that creatures breath including humans.
Resting respiratory rate in adult is 12 to 15/ minute. So it takes about 4 to 5 seconds for human breath to go in and out.
Answer:No, the moon is not stable for a human environment because it has no atmosphere to hold in oxygen for humans to breath. We also can't grow any plants because co2 will escape if there is no atmosphere. I watched a documentary on this.... it would take 500,000 years for the trees to produce enough oxygen to create an atmospheric shield.
usually what people does is cutdown trees and say the other people not cut.cuttingdown trees reduses the oxygen level in our atmosphere,take away the sheleter which provide by trees to birds,animals,mostly human beings.
they just take a deep breath and count to ten and if that is not working then squeeze something squashy so that you can take all of your anger out on it.
Trees "breathe" CO2 (carbon dioxide) through extremely small openings between the plants cells on the bottom of the leaf, called stomata (stoma singular). Through the same stomata O2 leaves the leaf.
