Classification/Taxonomy

1. Taxonomy is the science of grouping and naming organisms based on

______________________________________________.

2. Put the taxa in the correct order from largest (most kinds of organisms) to smallest (one kind of organism) CLASS, DOMAIN, GENUS, FAMILY, KINGDOM, ORDER, PHYLUM, SPECIES

3. Taxonomists use a two part naming system to identify an organism. The scientific name of

an organism is the and of the organism.

This system of naming is called .

Part A: In the exercises that follow, arrange the items listed into different groups. Give each group a title indicating what the members of that group have in common.

1. German Shepherd, Great Dane, parrot, Irish setter, canary, husky, robin, pigeon

Part B Study the following list of living things: Mare, trout, parrot, quarterhorse, woodpecker, spaniel, goldfish, Great Dane, eagle, bass, beagle, hawk, stallion, Dalmatian, shark

1. Classify them into two groups (give each group a name). Group 1 __________ Group 2 ____________

2. Using the same list of living things show how they could be classified into three groups.

Group 1 _____________ Group 2 ______________ Group 3 _____________

3. Using the same list, show how they could be classified into four groups.

Group 1 ______________ Group 2 ______________ Group 3 ______________ Group 4 ____________
