Question

Define the terms: identification, nomenclature, systematics, taxonomy.

Answer 1

Hint: Classification determines methods for organizing the range of life on Earth. Since life first appeared on Earth 3.5 billion years ago, many new sorts of organisms have evolved. Many of those organisms became extinct, while some have developed into this flora and fauna of the planet.

Complete answer:
Identification: Identification is "the practical side of taxonomy, the method of determining that a specific (organism) belongs to a recognized taxon." Or the method of nomenclature or naming is merely possible when the organism is described correctly and that we are known to what organism the name is attached to.
Nomenclature: The term nomenclature means the scientific naming of organisms consistent with a long time system. The naming of plants on a scientific basis is named botanical or plant nomenclature. In earlier days common names were in use which generally changes with different languages. After observing the problem with different common names one common internationally accepted name was used for a species, scientific names (Technical names) are introduced in sort of polynomial, binomial and trinomial systems of nomenclature.

Systematics: It deals with the classification of organisms that supported their diversities and relationships among them. The term was proposed by Linnaeus who wrote 'Systema Naturae'. Systematics may be a discipline of biology that explicitly examines the natural variation and relationships of organisms, and which incorporates the sector of taxonomy. It also deals with the relationships of various groups of organisms, reflecting evolutionary relationships.
Taxonomy: Taxonomy is that field of biology which deals with the nomenclature, identification, and classification of organisms. There are over a million known species on Earth and doubtless, several million more not yet identified. Taxonomists are liable for identifying, naming, and classifying these different species.
Types of taxonomy:
Morphotaxonomy, cytotaxonomy, chemotaxonomy, karyotaxonomy, numerical taxonomy

Note: The organisms are classified due to the following reasons:
- Classification makes identification and the study of a wide variety of organisms simpler.
- It reveals interrelationships among different groups of organisms to perform evolutionary studies.
- It provides information about the organisms and fossils of other localities too.
