It is needed by our body to carry out a significant process called respiration. Respiration is carried out as cell level and is often confused with normal breathing. Plants also need oxygen for respiration (note: oxygen is NOT needed for photosynthesis).

∙ 12y agobecause without oxygen we would all die because we wouldn't be able to breath.. oxygen comes from trees

How does the atmosphere keep oxygen inside?
Inside what? Oxygen is part of the atmosphere. The thermal velocity of its molecules are insufficient to escape earth's gravity (unlike hydrogen molecules which are fast enough).
How does earth atmosphere make conditions on earth on suitable for living things?
REASON ONE: ATMOSPHERE Earth has a breathable atmosphere. Oxygen is the gas that is required for the life of most creatures. This is present in Earth's atmosphere, along with nitrogen, and in water, along with hydrogen. Oxygen is constantly put into the atmosphere by plants and trees. Fortunately, Earth's atmosphere does not contain much carbon dioxide, a poisonous gas which makes up most of the atmosphere of planets like Venus and Mars. In densely-populated areas, carbon dioxide is more present. This is because cars and factories produce it. This causes the air to be polluted. The Earth's atmosphere is kept on the planet by its pull of gravity. Mars and Mercury are too small to keep atmosphere. As a result, Mercury has no atmosphere, and Mars' atmosphere is very thin, containing gases which have not managed to escape into space yet. Earth's atmosphere is thick enough to prevent poisonous rays of radiation from getting through it (this is what has happened on Mars).
Earths gravity as a percentage?
enough to keep us on it
Trees and other plants Which are important natural resources provide us with what?
Plants provide us with oxygen, shade, and their roots help to keep soil from eroding.
What 2 conditions must be present on a planet if it is to have an atmosphere?
enough mass to keep it in placesource to create the atmosphere gasses
What is the the earths moons atmosphere?
There is no atmosphere on the moon. There is insufficient gravity to keep an atmosphere there.
Which gases in earths atmosphere help keep surface temperatures warm enough for life?
carbon dioxide, methane, and water vapor.
Earths early atmosphere formed during the early Archean era which gas was generally absent from the atmosphere at that time?
Oxygen Please study this, & don't forget it so you don't have to keep looking up answers .
Why do people believe that preservation of the Amazon rain forest is a global concern?
People think it is a major concern mainly because it "IS" a major concern for those of us who would like to keep breathing the oxygen in earths atmosphere, and for those who would like their grand children to have free oxygen available via the earths biosphere.
What is the advantage of microorganisms?
the advantage of micro organisms is that they help to keep the balance in the atmosphere. micro organisms use nitrogen like humans use oxygen, so nitrogen is 71% in the atmosphere and oxygen 21% and carbon dioxide 0.04% so with the help these of organisms there is a balance in the air that's why they are called important
Animals help keep the gases in the atmosphere in balance by?
Plants and animals help to maintain a balance of carbon dioxide in the atmosphere by cellular respiration and photosynthesis. Photosynthesis releases oxygen and cellular respiration releases carbon dioxide.
How did lots of oxygen then get into the atmosphere?
Plants They take in carbon dioxide Then keep the carbon to grow and give out oxygen
How can people help keep earth's ecosystem in balance?
how can people help keep earths ecosistem in balance
How does the atmosphere keep oxygen inside?
Inside what? Oxygen is part of the atmosphere. The thermal velocity of its molecules are insufficient to escape earth's gravity (unlike hydrogen molecules which are fast enough).
How does the paint on a car help to keep it from rusting?
It covers the steel, which is mostly iron, so that it is not exposed to oxygen in the air. Rust is iron oxide, a compound formed when iron reacts with oxygen in the atmosphere. If the steel is not exposed to oxygen, it will not rust.
What two things does momentum count on to keep in act?
Outside earths atmosphere its Gravity, and on Earth its Mass and Velocity.
Respiration and photosynthesis keep the levels of carbon dioxide and oxygen in the atmosphere?
fairly constant
