During photosynthesis, plants use sunlight, water, carbon dioxide to create energy and oxygen gas is liberated as a by-product of this process. This process is carried out by the invertebrates, including fungi, bacteria and some insects which are collectively called as the decomposers. A plant does Photosynthesis to let off Oxygen for organisms to use. The entire process requires oxygen and releases carbon dioxide. The earth's crust comprises land and water, which is the lithosphere. This carbon di oxide is again, taken up by plants, for photosynthesis. Stages of the Oxygen Cycle. A Diagrammatic Representation of the Oxygen Cycle. You know that oxygen is a must for life. Enter your email address and name below to be the first to know. During this process, plants take in carbon dioxide (CO 2) and absorb water (H 2 O) with the help of their roots. The entire cycle can be summarized as, the oxygen cycle begins with the process of photosynthesis in the presence of sunlight, releases oxygen back into the atmosphere, which humans and animals breathe in oxygen and breathe out carbon dioxide, and again linking back to the plants.

View What are the steps in the oxygen cycle.docx from BS MISC at Central Bicol State University of Agriculture - Pili Main Campus (formerly CSSAC-Pili). Corrosion is an irreversible destruction caused to materials or living tissues as a result of an electrochemical reaction. thank you needed some help for a project. In this process, metals like iron or alloy rust when they are exposed to moisture and oxygen for an extended period of time and new compounds of oxides are formed by the combination of oxygen with the metal. What are the steps in the oxygen cycle? During the night, plants take in oxygen and release carbon di oxide, to maintain their metabolism. It is a biological process in which the oxygen travels through the lithosphere, biosphere, and atmosphere. The oxygen cycle is thus a biogeochemical cycle that describes the movement of oxygen within the earth’s three main reservoirs – the lithosphere (land), the hydrosphere (water), and the atmosphere (air), which make up the earth’s biosphere. The oxygen that is released by plants is used by humans, animals, and other organisms for respiration, i.e. It plays an essential role in most life forms on Earth and also serves as an essential element in biomolecules like proteins, and nucleic acids. The air in the atmosphere is composed of different gases, namely nitrogen (78%), oxygen (21%), argon and other trace gases (1%). Oxygen is used up in : Respiration – All organisms use oxygen for respiration. These methods are discussed below: Photosynthesis Plants undergo photosynthesis that helps them produce energy and food for themselves. Today, oxygen is freely available in the air, and also dissolved in water. Combustion: It is also one of the most important processes which occur when any of the organic materials, including fossil fuels, plastics and wood, are burned in the presence of oxygen and releases carbon dioxide into the atmosphere. It is also the most common element of the human body. The sum of Earth’s ecosystems makes a biosphere. Plants: The leading creators of oxygen are plants by the process of photosynthesis. Rusting of iron is the most common example. Which is why it is not a good idea to sleep under trees at night. What are the steps in the oxygen cycle? Login or Register above to download the content. Sunlight – Some oxygen is produced when sunlight reacts with water vapour in the atmosphere.
