What are hydroponics?
Hydroponics is the technique of growing plants using a water-based nutrient solution rather than soil, and can include an aggregate substrate, or growing media, such as vermiculite, coconut coir, or perlite. Hydroponic production systems are used by small farmers, hobbyists, and commercial enterprisRead more

See lessWhy do desert plants bloom at night?
Their blooming is controlled by low temperature. They are sensitive to the phases of moon. The desert insects eat away flowers during day time. In desert conditions, most of the activity of the plants and animals happens during the night because of very high temperature in the day time.

The organism that is benefitted is called the parasite, while the one that is harmed is called the host. A few examples of parasites are tapeworms, fleas, and barnacles.
See lessProducers in an ecosystem are?
Plants are considered producers since they can produce their own food from non-living sources through a process known as photosynthesis. In photosynthesis, plants use sunlight and carbon dioxide to produce organic compounds.

See lessHow much energy is transferred to the next trophic level?
On average, only about 10 percent of energy stored as biomass in a trophic level is passed from one level to the next. This is known as “the 10 percent rule” and it limits the number of trophic levels an ecosystem can support.

See lessAs soon as the train starts moving, the head of the passenger sitting inside leans backwards due to the?
From Newton's first law of motion, an object which is initially at rest will continue to do so unless an external force acts on it. Hence, when the train starts moving, the man is still at rest and hence appears to move backwards with respect to the train. This is called as Inertia of rest.

See lessthe Washing Machine work on the principle of?
The working principle of a washing machine is centrifugation. Centrifugation is a separation process that uses the action of centrifugal force to promote accelerated settling of particles in a solid-liquid mixture. The washing machine consists of a centrifuge for this purpose.

See lessWhat is the role of simple machines in human life?
Simple machines are useful because they reduce effort or extend the ability of people to perform tasks beyond their normal capabilities. Simple machines that are widely used include the wheel and axle, pulley, inclined plane, screw, wedge and lever.
