plants do it by photosynthesis.
And animals do it by respiration

How did oxygen come into the atmosphere according to evolutionists?
Scientists agree that significant amounts of oxygen were first put into the atmosphere by cyanobacteria which used and still use a process called photosynthesis to convert carbon dioxide and water into sugar and oxygen. The sugar is then used to build cell walls and in the metabolism. When plants evolved, they too carried out photosynthesis, putting even more oxygen into the atmosphere. Prior to the evolution of cyanobacteria, the metabolisms of organism relied on anaerobic processes.
Explain why you call oxygen an element even though oxygen gas in the atmosphere is made from molecules?
oxygen gas are indeed composed of molecules... ...molecules of O2 meaning every molecule of oxygen is usually two elemental oxygen atom put together
Describe 2 ways in which the atmosphere is important to life on earth?
The three reasons why the atmosphere is important is that the atmosphere traps heat from the sun, that way it keeps us warm and the ocean from freezing up. Also is important because it helps you from deadly rays from the sun like UV rays. Lastly it is it important because it helps you breath by giving Oxygen to us, then us letting put Carbon Dioxide to the plants and trees, and the plants give us Oxygen!!!! Its the Circle of Life!
What are the characteristics properties of earth that make life possible as we know it?
First of all, we are in what the scientists call the 'Goldilocks zone' because we are in the small region of space which is cold enough to hold water without it boiling, and warm enough to allow it to stay a liquid. Secondly, there is the atmosphere which contains 20% oxygen, allowing is to breathe and 78% Nitrogen, 1% Argon, 0.04% Carbon dioxide and various other gases. The atmosphere also blocks harmful radiation from the sun, such as the ozone layer blocking much Ultra violet radiation from reaching us. This atmosphere also prevents meteors from hitting the earth, producing shooting stars. There is also the abundance of plants which use the light from the sun to photosynthesise and produce oxygen, enriching our atmosphere. It is thought that if plants were to be put on Saturn's moon Titan, the mainly nitrogen atmosphere would begin to contain oxygen and therefore allow life to develop.
How many humans put greenhouse gases into Earth's atmosphere?
We all do . Reason ; because we inhale oxygen, and exhale carbon dioxide. There are some 8 billion (8,000,000,000) humans on Earth .
The process of photosynthesis produces?
Simply put...... energy for the plant to survive.
What organism added oxygen to your atmosphere and why?
Plants, trees, and grass put oxygen into the air.
Could you put more oxygen on mars?
only if an atmosphere is created
What gas does the plant put back into the atmosphere and who uses the gas?
The plant put back oxygen into the atmosphere and the humans (us) use the oxygen to breathe Oxygen is used by all living things as well as playing a part in oxidization Fire corrosion etc
How are some ways you can put the word atmosphere into a sentence?
Astronauts have to wear spacesuits when they leave the atmosphere due to lack of oxygen.

What is the source of much of the oxygen the atmosphere?
plant-like plankton in the ocean put out most of the oxygen in the atmoshere as a waste-product of photosynthesis.

What are the importance of atmosphere?
the importance of it is.............................................................................................................................................................................................................................................................................................wala lang!!!! the importance of it is.............................................................................................................................................................................................................................................................................................wala lang!!!! just put it this way, the atmosphere is like a BIG bubble. containing out earths oxygen, therefore we would be DEAD!!!!

What happens when you put a beaker over a candle and why?
Burning is a process that uses up oxygen. When all the oxygen in the beaker is used up, the candle will go out.
