Match the items in Column I with those in Column II:

Column I	Column II
(i) A home for living	(a) Large organisms particles
(ii) Upper layer of the	(b) All kind of soil soil
(iii) Sandy soil	(c) Dark in colour
(iv) Middle layer of the	(d) Small soil particles and packed tight
(v) Clayey Soil	(e) Lesser amount of humus

(i)- (b)

Soil is one of the most important natural resources. It supports the growth of plants and supplying water and nutrients. It is the home for many living organisms.

(ii)- (c)

The upper layer of the soil is dark in colour as it is rich in humus and minerals. The humus makes the soil fertile.

(iii)-(a),

In sandy soil, particles are quite large and cannot fit closely together. There are large spaces between them that are filled with air. Therefore, water can drain quickly through the spaces between the particles.

(iv)- (e)

The middle layer of the soil has a lesser amount of humus but more of minerals.

(v)-(d)

In clayey soil, particles are smaller in size and tightly packed together. There is no space between the particles for air. Thus, clay soil has the highest water holding capacity.
