Soil is a complex mixture, comprising of minerals, organic matter, water and living organisms. It determines the diversity of life in any area.
Plants need soil for support and also get nutrients to prepare their own food. Herbivore obtains food from these plant. And, carnivore is directly dependent on the herbivore.
Aquatic animals are also dependent on soil as a resource. These animals depend on aquatic plants for food , which in turn, require nutrients from the soil.
Hence, all living organisms directly or indirectly depend on the soil.

Suppose two bodies A and B of masses M and m are lying at a distance d from each other. Let the force of attraction between these two bodies be F. according to the universal law of gravitation;
- The force between the two bodies is directly proportional to the product of their masses.
F ∝ M × m
- The force between the two bodies is inversely proportional to the square of the distance between them.
F ∝ 1/d2
Combining both the equations:
F ∝ M x m/d2
Or F = G M x m/d2 i.
where G is the constant of proportionality and is called the universal gravitation constant.
By multiplying crosswise we get
F × d2 = G M × m
Or G = F d2/ M x m
The SI unit of G can be obtained by substituting the units of force, distance and mass as N m2 kg –2.
The value of G was found out by Henry Cavendish (1731 – 1810). The accepted value of G is 6.673 × 10–11 N m2 kg–2.

Tiny droplets grow bigger and heavy by more condensation which ultimately leads to the formation of clouds.
Clouds are formed by the process of evaporation and condensation.
Water evaporates from water bodies and rises up in the air. This air also gets heated.
Hot air carrying water vapour rises up. It cools down as it goes up.
Cooling causes condensation of water vapour, which leads to the formation of tiny droplets.

Before developing a hierarchy in classification, we need to decide which characteristics should be used as the bass for making the broadest divisions. Then we should pick up next set of characteristics for making sub-groups. This process must continue and each time new characteristics should be used. The characteristics that decide the broadest divisions among living organisms should be independent of any other characteristics. For example, nature of cells and form of the body is considered to classify organisms into broad divisions. The characteristics in the next level should be dependent on the previous one that will decide the subsequent divisions of the groups.
