how important is nitrogen to the abiotic and biotic

Varieties that are biotic (diseases, insects and pests) and abiotic (drought, salinity, water logging, heat, cold, frost) resistant can be developed by an increase in crop productio..

These include the non-living, physico - chemical factors such as air, water, soil and the basic elements and compounds of the environment. Abiotic factors are broadly classified under three categories. Climatic factors which include the climatic regime and physical factors of the environ..

Nitrogen - Nitrogen forms nearly 78% of the volume of air. Earlier, the useful significance of nitrogen was not known and it was considered to be inactive. At that time, nitrogen was considered important only because it was known to moderate the pro..

Climatic Factors - The properties of temperature, pressure, humidity rainfall, sunshine cloud and wind in a given place and time is called weather . The average weather conditions of an area, which includes atmospheric conditions, seasons. etc. constitutes the climate. Weather refers to the daily o..

Biotic community is an association of a number of interrelated and independent populations belonging to different species, in a common environment which can survive in nature. Biotic community comprises a number of populations of different species interacting between them and th..

Nitrogen is present in the elemental state in the atmosphere to the extent of about 78% by volume. Nitrogen is important for life processes in all living organisms. But, free nitrogen cannot be directly assimilated by the living cells. Therefore, it is desir..

The nitrogen cycle is complex as it depends on the activities of various bacteria. Nitrate in the soil is built up by plants into protein which is then passed on to animals, which eat the plants. The nitrogen from the protein is returned to the environment as ammonia (ammonifica..

Given a, b, c and d are non-zero real numbers, we can deduce other proportions by simple Algebra. These results are often referred by the names mentioned along each of the properties obtained. (1) If then bc = ad This property is known as INVERTENDO. (2) If , then ad = bc This property is..
