All biosphere ecosystems have well-organized functions, such as cycling nutrients through food chains, operating biogeochemical cycles, and maintaining the energy flow received by green plants through solar radiation.
Recently, it has been found that Photo Voltaic Cells cannot be popularly used for power generation on large scales. However, our scientists have discovered that the alignment of Carbon Nano Tube with the polymer composites substrate would give very high efficiency in Photo Voltaic Conversion.
Many squirrels had made nests in upper portions of offices by depositing huge balls of wool like materials between the rows of files and old registers. Many times and many men spotted some or the other squirrel coming to the rows of files and registers placed there since many-many years. But since squirrels usually don’t destroy papers, as I think, nobody ever tried to disturb them.

Substances that cause pollution of air are called as air- pollutants or atmospheric pollutants. These are fine Primary Pollutants that contribute more than 90 percent of global air pollution. These fine pollutants are carbon monoxide (CO); Nitrogen oxides (NOx); Sulphur oxides (Sox) and particulates. These pollutants can be put into two broad categories A. Gaseous Pollutants, and B. Particulates.
Our natural resources are known to have some specific qualities of their own. These qualities are known as natural qualities. It is due to specific natural qualities that different natural resources have been useful to us and to the whole biosphere. But now, the condition has changed considerably.
The information received by a receptor at the end of a dendrite sets of a chemical reaction that creates an electric impulse.
Sparrow or the House Sparrow taxonomically belongs to the family Passeridae. It is found in most parts of the world.
A forest is a highly complex and constantly changing environment. It is made up of a variety of living things like wildlife, trees, shrubs, wildflowers, ferns, mosses, lichens, fungi and microscopic soil organisms; and non-living things such as water, nutrients, rocks, sunlight and air. Trees are the biggest part of this complex community.
Studies and researches that are done in different fields from time to time show increasing complexities in organisms than their ancestors. These studies and evidences show many important evidences of organic evolution.
