Answer/Explanation:
1. The similarities among the organisms listed on the cards are they are all in the Eukarya domain and the Animalia kingdom. They are different for being under different phyla, classes and orders. The cards are also different for their different tiers of classification level.
2.
Western honeybee - Apis mellifera
Eukarya Animalia Arthropoda Insecta Hymenoptera Apidae Apis mellifera
Blackburnian warbler - Dendroica fusca
Eukarya Animalia Chordata Aves Passeriformes Parulidae Dendroica fusca
Fruit fly - Drosophila melanogaster
Eukarya Animalia Arthropoda Insecta Diptera Drosophilidae Drosophila melanogaster
Domestic dog - Canis lupus
Eukarya Animalia Chordata Mammalia Carnivora Canidae Canis lupus
American brown bear - Ursus americanus
Eukarya Animalia Chordata Mammalia Carnivora Ursidae Ursus americanus
Goldfish - Carassius auratus
Eukarya Animalia Chordata Actinopterygii Cypriniformes Cyprinidae Carassius auratus
Human - Homo sapiens
Eukarya Animalia Chordata Mammalia Primates Hominidae Homo sapiens
Domestic cat - Felis catus
Eukarya Animalia Chordata Mammalia Carnivora Felidae Felis catus
Bess beetle - Odontotaenius disjunctus

3. There are the phlya Chordata and Arthopoda.
4. The classes in the chart are Insecta, Actinopterygii, Aves and Mammalia.
5. The orders in the chart are Hymenoptera, Coleoptera, Diptera, Cypriniformes, Passeriformes, Primates and Carnivora.
6. The families in my chart are Apidae, Passalidae, Drosophilidae, Cyprinidae, Parulidae, Hominidae, Felidae, Canidae and Urisdae.
7. Homo sapiens (humans), Felis catus (domestic cat) and Ursus americanus (American brown bear) are related because they all are Eukarya Animalia Chordata Mammalia.
Drosophila melanogaster (fruit fly) and Apis mellifera (Western honeybee) are related because they are both Eukarya Animalia Arthopoda Insecta.
Canis lupus (domestic dog) and Ursus americanus (American brown bear) are related because they are both Eukarya Animalia Chordata Mammalia Carnivora.
Carassius auratus (goldfish) and Canis lupus (domestic dog) are related because they are both Eukarya Animalia Chordata.
8. It is important to classify living things to keep track of them all. There are many organisms which are more similar to each other than is obvious. For example, it seems unlikely that fruit flies and humans are related, but they have a few similar characteristics.
