Classification
The biological world is enormously diverse. There are about 8.7 million species of plants and animals is present on the earth. The variety of organisms that we can see around is called as the biodiversity. There has to be an approach that enables us to get an idea of a group of Organisms by studying a particular type. This calls for a systematic arrangement of organisms on the basis of their similarities and dissimilarities. Systematic arrangement of organisms on the basis of their relatedness is called taxonomy.
