levels of ecosystems

Biomass is the living matter in any organism. It is the amount of living time or energy available as food for the organisms of the next trophic level. The mass of organisms in each trophic level is called the standing cro..

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..

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 ..

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 interconne..

Biological diversity includes 3 hierarchical levels. a) Genetic diversity b) Species diversity c) Community and ecosystem diversi..

Globally sea levels have risen 4-8 inches over the last century. The high temperatures have already started melting polar ice caps sea icebergs and glaciers. This has released enormous amount of water. Warmer temperatures also heat water and make it expand; thus ocean levels ne..

Pyramid of Biomass - "Pyramid of biomass is the graphic representation of biomass present per unit area of different trophic levels, with producers at the base and top carnivores at the tip". The total amount of living or organic matter in an ecosystem at any time is called 'Bio..

The study of food chains helps in understanding some of the important aspects of the ecosystem in particular and environment in general. The food relationship among the different organisms in an ecosystem The food chains are the living components of the biosphere These are the v..

The most distinguishing characteristic of life is the boundless diversity in living forms. It is the total living (biotic) component of our bioshpere. Biodiversity can be defined as the variety and variability of all animals, plants and micro organisms found on earth. The diversity is due to the ge..

. These animals utilize this energy for their own metabolic activities. Here again some of the energy is released as heat. When primary consumers are eaten by secondary consumers, the same process is repeated at every step of the food chain. Here it must be remembered, that energy released as heat ..
