The conditions of a habitat remain changing abruptly and periodically. Abrupt changes in environment often do not give time to an organism to get ready and to face the challenges. As such the organism can survive only when it has sufficient abilities to tolerate these changes.
Living beings interact with each other, with members of other species, and with components of the abiotic environment in an…
There are many different types of technologies or technological models- such as Low-tech, Hi-tech, alternative, intermediate, appropriate, blended, hard, and soft technologies.
The Wind is Air in Motion. It is caused by differential heating of land, water, hills and mountain slopes by sun rays. About 25 % (i.e., 0.34 KW/m2) of incident solar radiation is dissipated as wind energy. There is kinetic energy in wind.
There are various uses of Solar Energy. Farmers in Traditional Farming Communities used to solarise fields by living them empty after a deep ploughing during summers. It killed insects and pests. Human skin synthesizes vitamin-D when exposed to sunlight for short durations. Mothers used to make their babies sleep in the sun after oiling their bodies during winters in order to keep them healthy and strong.
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.

The application of scientific knowledge for practical purposes, especially in industry, is called as technology.
practices of modernization have disturbed the quality of environment.
We have damaged ecosystems in the name of development. Wildlife too is facing danger. Our activities have impacted in such ways that animal population has fallen into a serious zone of danger.
Ever since the earth was inhabited, humans and other life forms have depended on things that exist freely in nature…
