Habitat, Ecological Niche, Biosphere, Biodiversity Total views (225)  
A habitat is where things live. It 's more than a home; it's more like a neighborhood. For an animal a habitat includes all the land the animal needs to hunt, gather food, find a mate, and raise a family. Different combinations of ecosystem LAWS (light, air, water and soil), together with variations in climate and topography, create different habitats. A shady area supports different species of tr ......

Ecosystem, Structure and Functioning of Ecosystems, Pond as Ecosystem, Food Chains, Food webs, and Food Pyramid Total views (226)  
The living world depends upon the flow of energy and the circulation of materials through the ecosystem. Earth can be considered to be a closed ecosystem as far as materials are concerned. Only solar energy comes to the earth continuously. This now of energy drives all biological process. Energy and materials flow through the ecosystem tog ether as organic matter; one cannot be separated from the ......

Biomes of the World Total views (227)  
In the earlier unit we examined the interaction and interdependence of biotic and abiotic Components of an ecosystem.

Man and Environmental Relationship, Resource Use and Ecological Imbalance with Reference to Soil, Forest and Energy Resources Total views (213)  
Man for hi s every requirement is depending on nature. Man is not a creator. It is only nature which creates, evolves everything. Nature has everything required by man, but whatever is in the nature have their own limitations. Man cannot use everything available in nature without any limits.

Man Made Ecosystems, Eco - Tourism, Man Made National Sanctuaries Total views (187)  
A biotic community lives in an environment which provides material, energy requirement and other living conditions into it. The entire biotic community together with the aboitic environment forms one of the intricate system called ' eco system'. The term 'eco system' was introduced by Sir Arthur Tansley in 1935. An ecosystem is defined as "a structural and functional unit of biosphere or segment o ......

Depletion of Ozone, Green House Effect, Acid Rain Total views (186)  
Ozone is highly concentrated in the lower part of Stratosphere. It is at a height of2030 Km from the Earth's surface. In this layer ozone is continuously produced and destroyed by the natural process by the absorption of ultra violet rays of solar radiation. As the oxygen concentration remains constant at 2 1 per cent, it is likely that normal degradation of ozone must occur to maintain the ozone; ......

Man Induced Changes in Environment Total views (184)  
Man is an important factor of the environment. Thus, man play an important role in the natural environment in different capacities such as 'biological or physical, 'social man', 'economic man', and technological man'.

Solid Waste with Special Reference to India Total views (188)  
In ancient cities, food scraps and other wastes were simply thrown in to the unpaved streets where they accumulated.

Environmental Hazards, Floods, Earth as Warehouses, Flood, Famine and Landslides Total views (179)  
Earth has been undergoing various changes since its formation and these changes adversely affect the human beings as well as the rest of the environment. Changes on the earth are caused by natural process or human factors; some of the natural factors are volcanic eruptions, earthquakes, draughts, floods, cyclones, soil erosion, deflation, mudflows, snow avalanches and other similar phenomena. Thou ......

Avalanches, Forest Fires and Green Revolution Total views (179)  
In the high lands avalanches are annual catastrophes, large masses of snow may accumulate on the steep ice slope of mountains, then break off, roll down as avalanches or snow - slides and cause damage.

Typically occurring in mountainous terrain, an aval ......
