the different ecosystem

Living organisms cannot live isolated from their non-living environment. Living and the non-living environment interact with each other to form a stable system. A natural self-sufficient unit of the world comprising a biotic community (living organisms) and its abiotic physico-chemical environment..

The environment in which the man and other organisms live is called the biosphere. The biosphere is made up of different regions that have different types of flora (plants) and fauna (animals..

Significance of Food Chains - 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 componen..

Biodiversity - Biodiversity refers to the totality of genes, species and ecosystems of a region. Biodiversity differs from place to place. The living world abounds with enormous biodiversi..

In nature there is always a kind of interdependence between different kinds of living organisms among themselves and also between biotic and abiotic components of ecosystem..

Energy is the capacity to do work. Solar energy is transformed into chemical energy by the process of photosynthesis, and is stored in plant tissue and then transformed into mechanical and heat forms during metabolic activities. The energy, in the biological world, flows from the sun to plants and ..

Water is essential for life. The types of plants and animals distributed in water bodies greatly depends upon the nature of water, fresh water or sea water. The organisms have to face different problems of water scarcity or abundance, so osmoregulation is required for their proper functi..

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..

Food Web - In nature, food chain relationships are not isolated. They are very complex, as one organism may form the food source of many organisms. Thus, instead of a simple linear food chain, there is a web like structure formed by these interlinked food chains. Such interconnected matrix of food ..

. In other words, the level following the previous one always receives less amount of energy. After studying various food chains and energy transfers in different ecosystems, Lindemann in 1942 gave the generalization called "The 10 per cent law". It shows that about 90% of the e..
