"What is purpose of classifying animals?" Animal World part 9

Before an exam you have to revise everything, or sometimes you read everything again, you can't read each and everything which is coming in your exams quickly. So, you divide it in subjects and subjects in chapters and chapter are divided into topics. Like this we can easily study and revise everything easily. 

In the same way ordering and classifying animals makes it very each to study them. Animal classification is the process of identifying, naming and organizing animal species. So, as there is a branch of science for each thing, for this (animal classification) the branch of science is called 'taxonomy'.

Animals; as we read in this previous article, can be broadly classified in two categories- Vertebrates which have backbone and Invertebrates which don't have backbone. So, there are around 8 million species in Kingdom Animalia (Animal Kingdom) in which most are invertebrates. Now my question to you people is that how many percent of animals are invertebrates (I mentioned this in the previous part).

Each organism is classified into Kingdom, class, order, family, genus and species. So, if I ask you how many kingdoms are there in all? What would you answer? There are five kingdoms in all. In which Animal and Plant Kingdoms are main, and out of them we are only studying about Animal Kingdom, but after we finish Animal World we will study more about plants.

So now let me give you information about all kingdoms-

1. Animalia Kingdom- This includes animals

2. Plantae Kingdom- This includes plants

3. Protista Kingdom- This includes single-celled organisms

4. Fungi Kingdom- This includes yeast, moulds, mushroom, etc.

5. Monera Kingdom- This includes Bacteria.

For some scientists there are these five kingdoms, and they include Arechaea and Bacteria in Monera kingdom only. But for some scientists they include Arechaea as a different kingdom.
