carbon
Through Crebs' cycle in aerobic respiration
Chlorofluorocarbons (CFCs) are a group of compounds that can damage the ozone layer by releasing chlorine atoms when they break down in the atmosphere. These chlorine atoms then react with ozone molecules, breaking them apart and leading to ozone depletion.
Fermentation and the Krebs cycle typically do not occur at the same time in cells. Fermentation is an anaerobic process that occurs in the absence of oxygen and produces lactic acid or ethanol as byproducts. The Krebs cycle, on the other hand, is an aerobic process that requires oxygen and takes place in the mitochondria to produce energy in the form of ATP.
The carbon cycle occurs when the carbon atoms are recycled over and over again on earth. The carbon cycle is the most important recycling cycle because carbon is present in every living thing on earth.
Short Answer: It is the continuous formation of ozone from oxygen, and the decay of that ozone back to oxygen. Oxygen absorbs UV-B or more energetic radiation (most commonly from our Sun), and dissociates into two separate oxygen atoms. Some of these singlet oxygen atoms combine with an oxygen atom to form ozone. Ozone has several decay paths, but all leave an oxygen molecule at the end: # Ozone encounters another ozone or singlet oxygen and only oxygen results. Ozone is inherently unstable and this does happen. # Ozone absobs UV-B or more energetic radiation (again from the Sun most commonly) and dissociates into an oxygen molecule and a singlet oxygen atom (some few of which will make ozone again). # Ozone encounters the long list of things that ozone will attack, and ozone loses a single oxygen atom to the reaction. Only #3 removes net oxygen from the "pool" of oxygen. There are additional pathways of forming ozone, where a nitrogen molecule temporarily stores the singlet oxygen, until an oxygen molecule is encountered and the payload can be delivered. There are mechanisms that block this "handoff" also, and they also remove oxygen from the "pool".
Photosynthesis is the process that produces oxygen gas in the oxygen cycle. During photosynthesis, plants, algae, and some bacteria use sunlight to convert carbon dioxide and water into glucose and oxygen.
Photosynthesis
its the by-product in the Calvin cycle or the light dependent reaction
The process that produces oxygen in the oxygen cycle is photosynthesis. During photosynthesis, plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce glucose and oxygen as a byproduct.
when you drink water, the hydrogen and oxygen atoms split and the atoms can be used in the calvin cycle.
Through Crebs' cycle in aerobic respiration
The carbon and oxygen cycle are related by complementary relationship. For example whenever animals and humans breath they breath in oxygen and breath out carbon. Another example is plant and trees tack in carbon for nutrients and releases oxygen.
Oxygen gas is produced during the process of photosynthesis, which occurs in plants, algae, and certain bacteria. These organisms use sunlight, carbon dioxide, and water to produce oxygen as a byproduct.
The Chapman Cycle is the cycle of O2 into O3 and back into O2. There is no net change because it's a closed cycle. 3O2+UV photon->O+O2+O3->3O2 It takes place in the Stratosphere.
Marine phytoplankton, particularly cyanobacteria, are believed to be responsible for producing roughly half of the oxygen on Earth through photosynthesis. These microscopic organisms play a crucial role in the oceanic ecosystems and global oxygen cycle.

Water cycle produces rain. The rain reaches earth's surface.
