ecosystems

The characteristic structure of an ecosystem is obtained by the systematic physical organisation of the abiotic and biotic components of that particular ecosystem. The two main structural features of any ecosystem are its 'species composition' and 'stratification'. An ..

The study of food chains helps in understanding some of the important aspects of the ecosystem in particular and environment in genera..

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..

Introduction - Biogeography reveals that living organisms (plants and animals) are found practically everywhere on this earth. The living components interact among themselves as well as with their physical environment like soil, air and water. The branch of biology, which deals with the relationshi..

Diversity at the level of community and ecosystem exists along 3 levels. It could be within-community diversity (alpha diversity), between-communities diversity (beta diversity) or diversity of the habitats over the total landscape or geographical area (gamma diversity). Biogeographical r..

Biome is a large, regional or sub continental biosystem characterized by a major vegetation type or other distinct landscape characters such as tropical deciduous forest, tundra biome, et..

The functional attributes of an ecosystem helps to keep its component parts running together. Few important functional aspects of an ecosystem ar..
