what is biogeochemical law

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. These nutri..

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..

Some of the major biogeochemical cycles in nature are carbon cycle, nitrogen cycle, oxygen cycle, water cycle, phosphorus cycle and sulphur cyc..

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 gaseous cycles, the elements have a main reservoir in the gaseous phase, and the reservoir pool is the atmosp..

A planet moves around the sun in such a way that the square of its time period is proportional to the cube of the semi-major axis of its elliptical orbit. If T is the time period of revolution and 'a' the semi-major axis then, for circular orbits a = r (radiu..

The study of behaviour of gases has led to the formulation of a few important generalisations called as Gas Laws..

Laws of Thermodynamics - Zeroth Law - The 'zeroth law' states that 'if two bodies (say A and B) are in thermal equilibrium with another body C, then the bodies A and B will also be in thermal equilibrium with each other'. This law is important as it helps in ..

The 'zeroth law' states that 'if two bodies (say A and B) are in thermal equilibrium with another body C, then the bodies A and B will also be in thermal equilibrium with each other'. This law is important as it helps in understanding the concept of temperatur..

The volume of a given mass of a dry gas is inversely proportional to its pressure, temperature remaining constant. Robert Boyle (1627 - 1691) discovered this law in 1662 and it was named after hi..
