TEK 8A

What is taxonomy?

• The scientific study of how living things are classified.

• The study of animal behavior in their natural habitats.

• The process of naming and identifying species based on their DNA.

• The examination of the evolutionary history of organisms.

Why is it important to use a scientific name for species?

• It helps in identifying the most dangerous species.

• It prevents confusion as to which organism you are studying; it is uniform no matter where you live.

• It is easier to remember than common names.

• It provides information about the habitat of the species.

Who is credited with creating the system for classifying organisms that is used today?

• Charles Darwin

• Gregor Mendel

• Carolus Linnaeus

• Louis Pasteur

What is the two-name system using Latin words to describe organisms known as?

• Dichotomous key

• Cladistics

• Binomial nomenclature

• Phylogenetic classification

As you move downward from Domain to Species in the taxonomy ladder, what happens to the number of organisms and the similarities among them?

• The number of organisms increases and similarities decrease.

• The number of organisms decreases and similarities increase.

• The number of organisms and similarities both increase.

• The number of organisms and similarities both decrease.

What is one of the benefits of a standardized classification system developed by Carolus Linnaeus?

• Better understand predator-prey relationships.

• More efficiently map out fossils.

• Have a common understanding and technique on the classification of organisms.

• Best study how organisms evolve.

Which rank in the biological hierarchy is directly above 'Genus'?

• Family

• Order

• Species

• Class

What does the term 'biodiversity' refer to?

• The variety of life in a particular habitat or ecosystem.

• The genetic variation within a species.

• The number of species within a specific habitat.

• All of the above.

Which of the following best describes the concept of 'phylogeny'?

• The study of animal behaviors.

• The evolutionary history and relationships among individuals or groups of organisms.

• The geographical distribution of species.

• The process of classifying organisms based on their physical traits.
