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 fo..

' (bio - living organisms; geo - soil, rock, etc, chemicos - elements and their compounds). These materials have been used again and again in the formation of new generations of the organism. In other words, the matter is continuously recycled. By definition, "The movement or circulation of biogene..

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..

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..

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..

Nitrogen is an important structural component of many necessary compounds, particularly proteins. Atmosphere is the reservoir of free gaseous nitrogen and nitrogen compounds are found in bodies of organisms and in the soil. Living organisms cannot pickup elemental gaseous nitrogen directly from the..

The atmosphere contains a pool of CO 2 . CO 2 is removed from the pool by the photosynthetic activities of plants. It is released back into the environment by respiration which is carried out by all organisms including those micro-organisms (decomposing bacteria) responsible for the decay of dead p..

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 gaseous cycles, the elemen..
