biogeochemical cycle sulphur cycle with diagram

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..

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

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 g..

Sulphur Cycle - Sulphur is an important component of most proteins, few vitamins and enzymes. Though sulphur occurs in gaseous form, as hydrogen sulphide (H 2 S) and sulphur dioxide (SO 2 ), the residence time of sulphur in atmosphere is v..

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..

Summary - The biotic and abiotic components form an interacting system called 'ecosystem'. Producers, consumers and decomposers are the various trophic levels, which are linked by their food relationship forming a 'food chain'. Several food chains are interrelated and interconnected to form a netwo..

In an ecosystem there are two processes proceeding simultaneously: 1 ) Energy flow and 2 ) Biogeochemical cycle The energy flow is in a single direction and is non-cyclic where as Biogeochemical flow is cyclic (Any mineral cycle..

The nutrient movement goes on side by side along with unidirectional flow of energy. The nutrient movement is a cyclic movement where the nutrients revolve round with an ecosystem, hence cyclic. This cyclic movement of nutrients is also called as biogeochemical cycle..
