Want this question answered?
The atmosphere on Venus is mainly Carbon Dioxide (around 96.5%) with around 3.5% Nitrogen.
no it is not a gas itself. it is a combinaton of gases consisting of: 78% nitrogen, 21% oxygen and the other 1% consiting of small amount of CO2, argon and other things.
We humans need the oxygen from the atmosphere. The 80% or so nitrogen is also very important, since otherwise the oxygen would be too concentrated, making it much easier for lots of things to burn almost explosively.
Venus is not made up of gas, but it does have a thick atmosphere. The main gas in the atmosphere is carbon dioxide, at about 96%. There's some nitrogen (about 3.5%) and traces of other things.
Two things the earth atmosphere keeps out are: Harmful radiation and Space debris
Since 78.08% of the Earth's atmosphere is composed of nitrogen, yes. But it cannot be used in biological processes. The nitrogen animals use comes in the form of nitrogen compounds acquired from food. Ultimately, the nitrogen used by most living things is produced by nitrogen-fixing bacteria which do use nitrogen from the atmosphere, these compounds are then taken in and used by plants.
no nitrogen can not directly use for living
The atmosphere, feces, urine, and plants
Things that composes the atmosphere are the nitrogen is about 78%and the helium which is 56% and the carbon dioxide we breath that is 28%
78% of the atmosphere is nitrogen, it is used in fertilizer and it is important in the human source
nitrogen makes up most of our atmosphere so i should hope it's not bad to breath it. it's purpose is to dilute the oxygen in our atmosphere. things would be more flammable if the nitrogen wasn't there
Carbon dioxide makes up over 90% of the atmosphere along with some nitrogen and traces of other things.
Many things. Titanium burns well in both oxygen and nitrogen.
The main components of the atmosphere are: Nitrogen (approximately 78%) Oxygen (approximately 21%) Argon (approximately 0.93%) Carbon Dioxide (approximately 0.038%) Along with other gases of a much smaller proportion.
The atmosphere on Venus is mainly Carbon Dioxide (around 96.5%) with around 3.5% Nitrogen.
No, not directly. There are bacteria that can fix Nitrogen out of the air and make it available as a nutrient but Nitrogen has to be in a compound form for it to be useful to most of the living things on Earth.
when an animal urinates nitrogen returns to the water or soil,and when organisms die and decay,nitrogen returns to the soil and eventually to the atmosphere
