Does ocean water have higher levels of oxygen than air?
I would say the air has the highest level of oxygen but it depends how high up you are.
Why could you say that plants are a sink for carbon?
Plants take in carbon from carbon dioxide in the air and convert it to carbohydrates and keep it with them.
What gas in the air reacts to sulphur when it burns?
Combustion products of methane would be water and CO2. Methane is CH4. http://en.wikipedia.org/wiki/Methane
What can you say about the relative density of oxygen?
i don't it's value but it definitely has it's own density since its volume is directly propotional to its volume.
Which living things carry out the process of respiration?
all living organisms respire during respiration they take in oxygen and give out carbon-dioxide during respiration the food present in the body is broken down with the help of oxygen to release energy
Why could you say plants are a sink for oxygen?
they produce oxygen
Do bees make oxygen?
They pollinate plants, and this is necessary to create new plants. The new plants create oxygen, so I would say yes. But, to be fair, they do it indirectly.
How do you process the air you breathe before it gets into your lungs?
All I can say is that when you breath in, you take in air and extract the oxygen. When you exhale you're letting out the nitrogen that was with the oxygen in the air. The oxygen then goes to your blood. How this happens? I can't say. Sorry.
How you take oxygen from air?
By inhalation or we can say that by inhaling
Does ocean water have higher levels of oxygen than air?

What light rays do plants absorb and which do they reflect?
Plants absorb Co2. Carbon dioxide. Which is Carbon and oxygen. The carbon is used in the plant and the oxygen is released, (or reflected as you could say).
What happens when you talk to plants?
Not in any big way. Some say that plants like the shot of CO2 they get when we are up close and breathing on them while we are talking to them, but they get all the CO2 they need from the air anyway. The real benefit in talking to your plants comes from the fact that if you are having a conversation with you're plant, you are probable getting pretty close to it. So you can spot any signs of trouble before they get out of hand. So, the answer is really yes and no. yes talking to plants effect their growth plants get co2 which is oxygen from the air but when u talk to them you are giving them a shot of co2 OK I say no because plants use carbon dioxide as their oxygen and let oxygen out for us to breath when we talk to the plants we are breathing on it giving it carbon dioxide which they breath on so NO it does not affect the growth it helps it so who ever say no is wrong so now you know the correct answer.
Does Planet Mercury have oxygen in the air?
some scientists say yes others no but most say no
What is the name of the compound made by plants and used by animals for fuel?
I'd say Oxygen.
Is the air you breathe nitrogen?
In the air, considering you do not live in a highly industrial area, is about 78% oxygen, 21% oxygen, and 1% water vapor and other things floating around in the air. So yes, you could say the air you breathe is nitrogen, and you could argue that, saying that your body expels all of the nitrogen. All animals (including us) require a minimum amount of oxygen in their system. Plants need carbon dioxide to live, and they breathe out oxygen like we do with carbon dioxide. It's sort of like a trade.
Why is air important for humans?
Yes, partially. Trees give us oxygen (which is a gas we breath). Most of the air in our atmosphere is made up of nitrogen (around 78%). Oxygen, carbon dioxide and water vapor make up the majority of the rest of the air, of which trees only give us oxygen. Oxygen is the second most common element in air though; so I would still have to say yes. Humans and most animals on our planet breathe in oxygen and breathe out carbon-dioxide. Yet trees breathe in the carbon-dioxide we breathe out and breathe out oxygen which we need to breathe in. Of course don't give us all our oxygen either. Most of the oxygen replenishment comes from sea weed (or sea algae). But the simple answer to your question is yes. Oh, and Al Gore is a liar. That is always a good ending to a good answer about the air in our atmosphere.
How long can you survive in a standard space suit in space?
Probably the rate limiting step is going to be your oxygen supply. Does this stranded astronaut have an umbilical supplying him/her with oxygen? Is the astronaut getting oxygen only from their backpack (PLSS)? Often these portable life support systems will supply fresh oxygen and use lithium hydroxide to scrub the exhaled carbon dioxide while recycling the suit's atmosphere. Another consideration is the amount of activity the astronaut is doing. The more active they are, the faster they will burn through their oxygen supplies. So, lets say there are two astronauts stranded on the moon. One is very active and is burning through the oxygen and lithium in his PLSS, he might last 4-6 hours. Let's say his comrade is laying very still--almost sleeping--trying to conserve his oxygen and lithium hydroxide. He might last 6-8 hours. There is an issue of electricity and water used to control the suit's temperature. If the astronauts kept themselves in the shadows (of the Lunar Module) they could save cooling water and electricity. Still, the amount of oxygen astronauts bring with them into space is finite. If they are stranded, they will eventually run out. In a larger space station, it would be possible to grow enough plants to PRODUCE enough oxygen to supply the astronauts with an ~unlimited supply of oxygen. However, if the astronauts became dependent on these plants for oxygen production, any problem with the plants (say, over exposure to sun light, under watering, etc...), could doom the crew.
