Question
How are organisms classified?
Solution
The classification of living organisms is based on their similar characteristics, body structure, and biological features.
- All organisms are first classified into living and non-living categories.
- Then, living organisms are further divided into two main groups: Plants and Animals.
- Animals are classified into different groups based on their body structure, such as:
- Vertebrates (Ksheryuki) and Invertebrates (Aksheruki)
- Mammals, Birds, Reptiles, Amphibians, and Fishes
The scientist Carl Linnaeus developed the Binomial Nomenclature system, which is used for the classification of living organisms.
