function of the sulphur cycle

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..

Water Cycle or Hydrological Cycle - Water is an indispensable commodity of life. Water determines the distribution, structure and function of organisms in the ecosystem. Water occurs in three phases - solid, liquid (ice/snow) and gaseous (water vapour). In liquid phase..

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..

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 gaseous pha..

1) Decomposers like Aspergillus (aerobic fungi), Neurospora (aerobic fungi) and Escherichia (anaerobic bacteria) act on the dead and decaying organic matter of plants and animals, releasing hydrogen sulphide (H 2 S) to the environment. 2) Heterotrophic bacteria like Desulfavibrio and Acetobacter r..

It is the most abundant cation in plants. 1. Required for the metabolic activities of cells in young growing parts like root tips and young leaves but seeds are an exception. 2. Essential for the functioning of about forty enzymes which take part in glycolysis, Kreb's Cycle, pho..

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..
