oxygen cycle in the taiga

The Taiga Biome - Taiga are the 'northern coniferous forests' which are also referred as 'North Woods', very common in Siberia. Taiga extends as an east - west band across North America, Europe and Asia, just to the south of tundra (between 45 o N to 75 ..

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..

Carbon Cycle - 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 o..

Kreb's Cycle - 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 gro..

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..

Earth is the source of matter for all living organisms, as they require several (about 40) elements for their growth and life processes. Some elements and their compounds have an important role in the living protoplasm and are required in large amounts. These nutrients are called 'macro nutrients' ..

Nitrogen Cycle - Nitrogen is an essential constituent of animal and plant matter as it forms proteins, which are the building blocks of life. The ultimate source of nitrogen is atmospheric nitrogen but neither plants nor animals are capable of assimilating free nitrogen. Thus the process ..

The oxidation of pyruvic acid into CO 2 and water is called Krebs cycle..

It takes place in the mitochondria. The pyruvic acid formed during glycolysis is oxidized 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 releas..
