Classification (3.5) Review 2

Classification is the process of organizing living organisms into groups based on shared characteristics and evolutionary relationships.

A taxonomic group, or taxon, is a category in the biological classification system that includes organisms with similar characteristics.

Evidence showing birds shared a common genetic history with dinosaurs.

A dichotomous key is a tool that allows the identification of organisms by answering a series of questions that lead to the correct name.

Caddis flies belong to the order Trichoptera.

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.

The kingdoms Animalia and Fungi contain only heterotrophs.

The main difference is the chemical composition of their cell walls.

Fungi are primarily multicellular, heterotrophic organisms that absorb nutrients from their environment.

A taxonomist classifies organisms based on their characteristics and evolutionary relationships.
