Species are considered as
- Real basic units of classification
- The lowest units of classification
- Artificial concept of human mind which cannot be defined in absolute terms
- Real units of classification devised by taxonomists
The Correct Option is A
Solution and Explanation
Species are considered as real basic units of classification.
In biology, among the major taxa in the taxonomic hierarchy, a species is one of the basic units of biological classification. A species is defined as the largest group of organisms capable of interbreeding and producing fertile offspring. As they share more common characters, they form the lowest basic unit of classification. The species have a real existence making the most suitable answers amongst the provided options.

Questions Asked in NEET exam
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :

Concepts Used:
The Living World
- The living world includes a vast variety of living organisms like plants, animals, and even microorganisms that exist on the earth.
- These organisms also differ in size, color, habitat, physiology, and morphology.
- Biologists have developed certain rules and principles supplementary which are helpful in the identification, nomenclature, and classification of organisms.
- Such rules and principles lie in Taxonomy.
- The taxonomic studies are very helpful and useful in specific fields like forestry, industry, agriculture, and for knowing our bio-resources.
- All discovered living organisms are being named so that they are known by the same name throughout the world.
- Each biological name is a collection of a generic name indicating the genus of an organism and a specific name that indicates the species.
