What is the process by which anything is grouped into convenient categories based on some easily observable characters?
The process by which anything is grouped into convenient categories based on some easily observable characters is known as classification. It involves identifying distinctions among organisms and placing them into groups that reflect their most significant features and relationship.
How are living things classified?
This classification can be done by dividing the organisms into huge groups based upon the fundamental characteristics that are shared between all the living beings in the group. These bigger categories can be divided into further subcategories based upon the increasing number of shared qualities amongst them. Going forward the characteristic may be less defining for the whole bigger group but it will still be important for their own smaller group. For example, if all the animals in a group, will have some fundamental similarities such as the existence of limbs, their multicellularity, etc. But there will be significant differences between a cow, a wolf, a human being, etc. After understanding in good detail why are living organisms classified understanding the basis of classification becomes equally important which is explained further.

How are diverse organisms classified?
Ans: The diverse variety of organisms are classified on the basis of their very basic shared characteristics. These large groups can further be classified into smaller groups with an increasing number of shared characteristics amongst the organisms. This idea led to the modern classification of living organisms based on kingdoms.

How many organisms are there on Earth?
Total numbers of organisms already discovered are about 8.7 millions. Among them 6.5 millions are terrestrial and 2.2 millions are aquatic.The largest group of organisms are arthropods, contains about 75% of the total animal community. Discovery of living organisms every year is a continuous process. Every year almost 15000 new species are discovered. It is estimated that total living organisms including terrestrial, aquatic and aerial are ranges between 5 to 30 million species. We all know that two thirds of entire earth is consists of water. It includes huge oceans, seas, rivers, lakes etc. Many portion of the aquatic area are still undiscovered. As the depth of oceans and some seas are very high and shallow area donot allow sunlight to enter and touch the floor of the sea and oceans. As a result it becomes quite difficult to go there and observe the biosphere. Not only oceans but in some tropical rain forest are also there , where identification and study of different organisms are tough due to adverse weather. About 50 to 100 times more species have been extinct due to bad weather, insufficiency of food, or improper living place. Even according to Darwin’s “survival of the fittest “indicate there is always competition between the two species of same habitants. Winner will be accepted by the nature. Besides this if a community is unable to adjust itself with changes of environment will be extinct automatically in nature.
What is the binomial nomenclature?
6. Binomial nomenclature: different organisms are called by their local name. So it is being difficult to establish discussion about the organisms in different state, countries and continent. For this binomial nomenclature has been created according to the units of Classification (kingdom, phylum,class,order,genus, species).As a result an unique name of each species were established (species and genus).

Modern System of Classification
- Two kingdom system of classification
This system of classification is the oldest and it was suggested by Carolus Linnaeusin 1758. He divided the living world (organism) into two kingdoms, Plantae (for all plants like trees, shrubs, climbers, creepers, moss, and floating green algae) and Animalia (for animals). - Three kingdom system of classification
