7.2 biologist use Seven Levels of Classification
Dichotomous Key
A series of questions, each with only two answers, that can be used to help identify an organism's species and genus
no, they can be further subdivided
Are all of the turtles in the family level the same kind of turtle? explain?
more because they are broken down into the groups that they are most similar to.
As the animals get closer to the species level, do they share more or few characteristics?
field guide
Has pictures of animals or plants. It can help determine visual similarities, but may be incomplete. It can help narrow down possible organisms.Can be time consuming
it offers two choices
How does a dichotomous key work?
2
How many choices are you given for a dichotomous key?
dichotomous key
Is a series of questions with two possible answers for each question
size, coloration and age
Predict what differences you might find among organisms in the same species.
genus
The first part of a binomial name that groups together closely related species. The genus Felis includes all species of small cats
Binomial Nomenclature
The two part naming system used to identify species the first part of the name is the genus and the second part of the name is the species.
number of veins on the leaf, teeth or lobes, bristle or no bristle on the leaf tip, shape of leaf, veins that are in teeth, or more teeth side veins
What characteristics in the key are used to identify the tree?
A two part naming system
What is binomial nomenclature?
the two part naming system that uses the genus and the species an organism
What is binomial nomenclature?
A genus is a group of species that have similar characteristics. One or more species make up a genus
What is the difference between genus and species?
homo sapiens
What is the genus and species name for humans?
Kingdom
What is the highest level of classification?
apple, all of the questions answered directed you to the apple leaf on the key
What is the identity of the tree shown in the picture? How do you know?
each has only two choices. This eventually leads to the identification
What makes a dichotomous key easy to use?
genus
What term describes a group species with similar characteristics?
dichotomous key and field guides
What two tools have taxonomists developed to identify organisms?
he developed systems for both naming species and organizing them into groups
What were Carlous Linnaeus's main contributions to taxonomy?
alligator and snake
Which animals were eliminated at the order level because they are not turtles?
bird, frog,and monkey
Which animals were eliminated from the levels of reptiles?
species
Which is the most specific level of classification?
kingdom
Which level of classification in the seven-level system includes the most species?
The species
Which name of a specific name comes second?
all of them
Which of the organisms in the first level belong to the animal kingdom?
kingdom,phylum,class,order,family, genus, species, kingdom contains the most organisms
Write the names of the seven levels of classification. Which contains the most organisms?
