      • El oxígeno es un elemento químico de número atómico 8 y número de masa (peso atómico) 15,9994 uma, representado por el símbolo O. Su nombre proviene de las raíces griegas ὀξύς (oxys) (‘ácido’, literalmente ‘punzante’, en referencia al sabor de los ácidos) y –γόνος (-gonos) (‘productor’, literalmente ‘engendrador’; es decir, "productor de ácidos"), 1 ​ porque en la época en que se le dio esta denominación se creía, incorrectamente, que todos los ácidos requerían oxígeno para su composición.

    Oxygen cycle refers to the movement of oxygen through the atmosphere (air), biosphere (plants and animals) and the lithosphere (the Earth’s crust). The oxygen cycle demonstrates how free oxygen is made available in each of these regions, as well as how it is used. The oxygen cycle is the biogeochemical cycle of oxygen atoms between different ...

  3. Most living things use oxygen in respiration. Many molecules in living things have oxygen in them, such as proteins, nucleic acids, carbohydrates and fats. Oxygen is a part of water, which all known life needs to live. Algae, cyanobacteria and plants make the Earth's oxygen gas by photosynthesis.

  5. May 2, 2024 · Oxygen is a colourless, odourless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere. Oxygen forms compounds by reaction with practically any other element, as well as by reactions that ...
