what are the 3 types of biogeochemical cycle

Types of Biogeochemical Cycles - Biogeochemical cycles are basically of two types: a) Gaseous cycles like carbon (as carbon dioxide), oxygen, nitrogen, etc. b) Sedimentary cycles like sulphur, phosphorus, etc. In gaseou..

In gaseous cycles, the elements have a main reservoir in the gaseous phase, and the reservoir pool is the atmosphere or water. The biogenetic materials involved in circulation pass through a gaseous phase before completing the cycle..

Biogeochemical Cycles - 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. T..

The C 3 type of carbon reactions occurs in the strome of the chloroplast. It is also called Calvin cycle after its discoverer, Melvin Calvin. a) In the first step CO 2 is accepted by a 5- carbon molecule, ribulose -1,5 biphosphate (RuBP) and 2 molecules of 3..

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..

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 of oxygen for aquatic organisms..

In BC = 4.5 cm, AB - AC = 1.6 cm (1) Draw BC = 4.5 cm. (2) At B make an (3) On BX cut off BD = 1.6 cm join DC. (4) Draw perpendicular bisector of DC to cut BX at A. (5) Join AC The..

The heart has an increasing rhythmic activity. It pumps blood by its contraction and relaxation. The contraction of the heart is called systole and the relaxation is called diastole . The contraction and relaxation together constitute the heart beat. The heart beats at the rate of 72 beats per minu..
