endangered ecosystem summary

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..

Steps for conservation of wild life include protection of all threatened species in their natural habitat, preservation of the ecosystem and safeguarding of critical habitat..

Although India's food production has increased by 300 percent, percapita availability of food has reduced, in the last 50 years. Human food needs are met by cereals, millets, pulses, oilseeds, fishes, milk products, poultry birds, eggs and fishes. There is serious malnutrition problem in In..

Summary - Wild life and forests make our biotic resources Wild life maintains food chains and natural cycles, has immense value as gene banks for breeding programmes. Although creation and extinction of species is a natural phenomenon, elimination of species has become extremely rapid dur..

Nitrogen Cycle - 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 ..

Summary - Man has to be dependent on natural resources despite all the scientific inventions Natural resources could be classified into geographical, hydro-geological, atmosphere, edaphic, forest, crop, wildlife, marine / aquatic, animal, human and microbial resources Natural resources ar..

This is conservation of living resources within the natural ecosystem in which they occur. This is acheived by protection of natural habitat and maintenance of endangered species in certain protected areas such as national parks, wild life or bird sanctuaries and biosphere rese..

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..

. For example, more land was converted to cropland in the thirty years since 1950 than had been converted in the whole of the period 1700 to 1850 (The Biodiversity Synthesis Report in the UN Millennium Ecosystem Assessment project). Forty percent of the earth's land surface is now used to..
