Reproduction and Variations
Living beings develop their population through reproduction. But reproduction is the process through which different traits appear in living beings. Variation is essential for evolution
Modern Agriculture and Monoculture
More than half of the population of the world comprises farmers. These farmers know that maintaining and conserving natural resources are very important to sustain their lives. However, the demand of more and more food due to the exploding population and higher expectations for comfort and wealth enforces these farmers to exploit more and more of the natural resources through the application of modern technology. The agriculture based on the latest farm machinery, hybrid and high-yielding crop varieties and agrochemicals is called as modern agriculture. Under the changing trends of modern agriculture, the difficult situation of maintaining and conserving natural resources is being faced the world over in the agriculture sector.
Grow Salai Trees for Health and Economic Growth
Salai tree or the Boswellia is the tree of economic and medicinal importance.
Recycling and Paper Industry
The process of recovering or reusing usable materials from discarded waste is called recycling. For example, about 15 per cent of Sulphuric acid is recycled in chemical manufacturing. In the early days, all the sulphur needed for the production of sulphuric acid was taken out of mines directly. But now, with the prevailing tendencies of recycling, sulphuric acid manufacturing industries are using sulphur from smelters, refineries, etc.
Urban and Rural Waste: Methods of their Disposal
Different activities may generate waste which may be solid or liquid. The quality of both solid and liquid wastes is increasing and if the wastes are disposed in an uncontrolled manner these may cause adverse impact on public health and environment. Hence these wastes need to be managed efficiently so as to safeguard public health and environment.

Living beings have many processes in common. Among all the common processes there is one very interesting and wonderful process…
Animals : domestic and wild
Animals can be categorized mainly into two categories- domestic, and wild. However, the domestic animals that live under wild conditions are called Feral Animals.
Energy from Oceans- Tidal Energy, Wave Energy and Oceanic Thermal Energy
Ocean is a vast natural resource of water. These have also been examined in the search for alternate sources of energy-generation. For example, gravitational pull, by sun and moon causes tides, in which sea level rises and falls, two times in 24 hours. When it rises, sea water may be diverted through suitable channels, to inshore reservoirs driving the turbines, during its entry.
What is respiration and how is it different from breathing?
