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 wate..

Ecosystem - Structure and Function - 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 ..

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..

Summary - In the modern system of classification, living organisms are grouped under five kingdoms, as proposed by Whittaker (1966). The Kingdom Monera includes bacteria and blue green algae, both of which possess prokaryotic cells. Bacteria are unicellular prokaryotes that have..

Cells vary in shape and size. They may be oval, spherical, rectangular, polygonal, spindle shaped, star shaped, rod-shaped or totally irregular like the nerve cell. The diversity in cells is in accordance with the role or function it has to perform as part of the tissue or organ syst..
