Dichotomous Key DOL

Tool used by a taxonomist to identify an unknown organism is a:

• dichotomous key
• binomial nmenclature
• scientific name
• binomial key

The scientific name for an organism is made from the:

• class and family name
• genus and species name
• domain and kingdom name
• kingdom and phylum name

When using a dichotomous key to identify organisms, what do we look at?

• internal and external structures

• cosmetic appearance, such as color

• environmental factors

• diet and mating patterns

An illustration and a dichotomous key are given. What is the correct classification for this organism?

• Class Insecta
• Order Amblygygi
• Order Araneae
• Order Scorpiones

Using this dichotomous key, identify the name of the circled Fish, J.

• peacock flounder
• band-tail puffer
• trumpet fish
• spotted goat fish

Using this dichotomous key, identity the name of the circled fish.

• band-tail puffer
• spotted goat fish
• peacock flounder
• trumpet fish

The 8 levels of classification, most broad to most specific.

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