the cycle of oxygen

Oxygen Cycle - Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rocks. Dissolved oxygen in water is the source o..

Annie covers a distance of 40 miles by walking for 3 hours and cycling for 2 hour. The next day she covers the same distance by walking for 2 1 2 hours and cycling for 2 1 2 hours. Assuming that her walking rate and cyclingh..

The oxidation of pyruvic acid into CO 2 and water is called Krebs cycle. This cycle is also citric acid cycle because the cycle begins with the formation of citric acid. Citric acid is a carboxylic acid containing 3 COOH groups. Hence this cycl..

Organic materials synthesised by the producers are eaten and assimilated by the consumers. With the help of decomposers, all the organic materials in the bodies of the consumers are eventually broken down into inorganic materials. These are then rebuilt into organic compounds by the synthetic activ..

Carbon is found as graphite and diamond in nature. It also occurs as carbon dioxide in the atmosphere. Because of the position of its electrons, an atom of carbon can form covalent bonds with hydrogen, oxygen, nitrogen, phosphorus and other carbon atoms. Because of this versatility, the c..

It takes place in the mitochondria. The pyruvic acid formed during glycolysis is oxidised and forms carbon dioxide and water. This reaction also releases molecules called the coenzymes: NADH 2 and FADH 2 . The hydrogen atoms associated with these are the hydrogen atoms release..

The atmosphere contains a pool of CO 2 . CO 2 is removed from the pool by the photosynthetic activities of plants. It is released back into the environment by respiration which is carried out by all organisms including those micro-organisms (decomposing bacteria) responsible for..

It is the movement of water between aquatic systems, air and land water vapour condenses to form clouds, and eventually rainfall. Plants play an important role in this cycle by the process of transpiration. The upper limit (maximum) of water availability of a soil is called field capac..
