Classification of Living Things

Why do scientists classify and organize organisms?

• To keep a list of all living things on earth

• Because it is fun

• So that they can note similarities and differences in different organisms and to avoid confusion when studying them

• So that each organism know their name

What is taxonomy?

• The study of living thing

• the branch of science concerned with the classification of living organisms

• the study of how living things interact with their environment

• the branch of science concerned with studying the animal kingdom

What are the 7 levels in order used to classify organisms?

• Domain, Kingdom, Species, Class, Order, Family, Genus, Phylum

• Kingdom, Domain, Order, Class, Genus, Species, Family, Phylum
