4. Grasshopper

Which of the following taxonomic category is less general in characters as compared to the taxonomic category ‘Genus’?
1.  Species
2.  Division
3.  Class
4.  Family

Species are considered as:-

1. Real basic units of classification

2. The lowest units of classification

3. The artificial concept of the human mind which cannot be defined in absolute terms

4. Real units of classification devised by taxonomists

Biosystematics aims at: -

1. The classification of organisms based on broad morphological characters

2. Delimiting various taxa of organisms and establishing their relationships

3. The classification of organisms based on their evolutionary history and establishing their phylogeny on the totality of various parameters from all fields of studies

4. Identification and arrangement of organisms on the basis of cytological characteristics

Which arrangement is in correct ascending order:
1.  Species < genus < order < family
2.  Genus < species < family < order
3.  Order < family < genus < species
4.  Species < genus < family < order

Practical purpose of taxonomy or classification is to :
1.  facilitate the identification of unknown species
2.  explain the origin of organisms
3.  know the evolutionary history
4.  identify medicinal plants
