Taxonomic classification - Quiz
Contributed by: Grant
  • 1. Taxonomic classification is a hierarchical system used to categorize and organize living organisms based on their characteristics and evolutionary relationships. It starts with the broadest categories, such as domain and kingdom, and becomes increasingly specific down to the species level. This system helps scientists understand the diversity of life on Earth by grouping organisms into related groups, making it easier to study and compare different species.

    Which scientist is known as the 'Father of Taxonomy'?
A) Alfred Wallace
B) Gregor Mendel
C) Carl Linnaeus
D) Charles Darwin
  • 2. Which taxonomic rank is below Class and above Family?
A) Species
B) Order
C) Genus
D) Phylum
  • 3. Taxonomic classification helps in understanding the ______ of organisms.
A) Age
B) Habitats
C) Diet
D) Relationships
