Classification 2020

Solange found a bird that fell out of its nest. She used a dichotomous key to help her decide what type of food it eats. She concluded that the bird she found eats grub worms. What information about the bird led her to this conclusion?

• The bird has talons and a short, pointed beak.

• The bird has webbed feet and a throat pouch.

• The bird has webbed feet and a short, round beak.

• The bird has talons and a long, pointed beak.

Organisms classified using a dichotomous key are based on

• physical characteristics

• geographic area

• behavior

• genes

A standardized taxonomic system, written in Latin, assigns each species a unique name. This action helps biologists avoid

• Classifying species

• researching species

• confusing species

• naming species

The pictures below show three organisms that Yolanda found outside.

Based on the Linnaean system of classification, how would these organisms be organized?

• They would be classified differently, because they each start with different letters.

• They would be classified together, because they all have cells of the same size.

• They would be classified differently, because they belong to different kingdoms.

• They would be classified together, because they were all found in the same area.

Which statement best describes a dichotomous key?

• A dichotomous key is a tool that identifies an organism based on traits.

• A dichotomous key is a tool that identifies an organism based on location.

• A dichotomous key is a tool that identifies an organism based on population size.

• A dichotomous key is a tool that identifies an organism based on reproduction method.

The list describes examples of several ways organisms obtain energy:

Organism A eats other living things for food.

Organism B gets food from parts of decomposing matter. Organism C makes its own food.

Organism D absorbs food from what it lives in or on.

Select the organism that would be classified as a member of the plant kingdom.

• Organism A

• Organism B

• Organism C

• Organism D

Under the Linnean system, a mushroom was classified as a plant. Select the question that would illustrate a problem with this classification.
