Photosynthesis
Oxygen is the gas that is used up when substances burn. The reaction between the substance and oxygen produces heat and light energy.
Oxygen is obtained from the atmosphere by a process called Respiration, this involves inhaling air and filling small air sacs in the lung, at which point the oxgen passes into the bloodstream through a process called Diffusion.
Oxygen is a gas, therefore it is colourless.
oxgen
If you mean "oxygen", that's "oxígeno".
Oxygen's symbol is O, and oxygen in its natural gas state is O2
Oxygen is an element, with an atomic number of 8.
Oxygen from the atmosphere is critical for the survival of most living organisms, as it is essential for cellular respiration, the process that releases energy from food. It is used by humans and other animals to create energy from nutrients in our bodies. Plants and photosynthetic organisms also utilize oxygen to perform photosynthesis, which produces oxygen as a byproduct and is essential for their survival.
Neither, Oxygen is a pure substance not a mixture.
The final products of photosynthesis is oxygen.
A rock my have a reddish color if it has iron in it and is oxgen rich. Oxidation.
Plants and animals are both complex organisms that share in a cycle of carbon dioxide and oxygen. Animals breathe out carbon dioxide when they respirate and plants take that in through their leaves and then emit oxgen which animals inhale. And the cycle begins again.
