The space between soil particles on the surface of earth is called pore space. It is of two types - micro and macro pores. Most of the water is held in micro pores. Pores, which are available for plant roots. Surface soil pore spaces are generally filled with air and water. Wate..

(a) Write 0, 1, 2, 3, 4 over each column as shown above. (b) Divide each number by 4 and take the square root. The values obtained are sine ratios. (c) Write these ratios in reverse order and you obtain the cosine ratios (sin A = cos B if A + B = 90 o ) (d) Divide each sine ratio by cosi..

The process is the transformation of gaseous nitrogen into nitrates by living organisms. Biological nitrogen fixation occurs by: a) Symbiotic nitrogen fixation, which is brought about by certain bacteria such as: i) Rhizobium species in the root nodules of legumes (pea family) ii) Nostoc..

When the water enters the soil and passes through the spaces between the soil particles and reaches the water table, the type of soil water is called gravitational water. This water lies far below and is generally not available to the plant roots..

. The spores also help in tiding over unfavourable conditions as they are covered with a thick wall. Fragmentation takes place in some lower plants and animals such as some worms. The mature organism breaks up into two or more pieces or fragments. The fragments then grow into complete organisms. Re..
