Decreases if meristems is removed to decrease demand for photosynthesis. It increases at the time of increased synthetic activi..

One crop component requires more nutrients and the other requires lesser nutrients. Mixed cropping is done to reduce the competition between component crops for light, nutrients and water. If one crop fails due to shortage of moisture or insufficient availability of nutrients, the other crop can c..

Oxygen-consuming wastes comprise of raw sewage from municipalities and other wastes from paper mills, tanneries, food-processing plants and agriculture; these cause a proliferation of aerobic decomposers who consume dissolved oxygen (DO) in water more rapidly than it can be replaced by the atmosph..

Practical Applications of Reflection of Sound - Some applications of the principle of Reflection of Sound are: (1) Megaphone, (2) Hearing Board, (3) Sound Board..

Practical Applications of Joule's Heating - This heating is inevitable in any electrical circuit. Since the energy lost by the flowing charges ends up as disorderly thermal motion, the phrase 'ohmic dissipation' is also used to describe it. Often, this is an undesirable effect. For exampl..

Megaphone: Megaphone is a horn-shaped tube. The sound waves are prevented from spreading out by successive reflections and are confined to the air in the tub..

Another unit of force by which the magnitude of force can be understood and gauged, is the gravitational unit of force. A gravitational unit of force is that force with which the Earth attracts a body of unit mass towards its centre. A gravitational unit of force may also be defined as that force w..

This heating is inevitable in any electrical circuit. Since the energy lost by the flowing charges ends up as disorderly thermal motion, the phrase 'ohmic dissipation' is also used to describe it. Often, this is an undesirable effect. For example, in electric circuits, the heat produced in a small ..
