What's the function of a dichotomous key?

My Answer: Dichotomous Key use by scientists are arranged in steps with two descriptive statements at each step.

Is my answer to this question is correct???

BTW: I got this answer from my textbook in that section that my science teacher assign the class to do for homework tonight and answer 3 questions.

Your answer is not correct. The question asks what is the purpose of the dichotomous key.

Answered by Laruen
ok...

I'll go back to my textbook and then I'll post my answr again to see if I'm right.
Answered by Laruen
The purpose of a dichotomous key is to take an organism, say a confier tree, and make note of its features and then look at a dichotomous key to identify what species it is based on its features.

Answer
Examine the two spiders.

Two spiders, side by side. One spider is black with eight segmented legs and a long, thin body. The other spider is brown with eight segmented legs and a short, wide body.

Which characteristic would best identify the spiders as belonging to different species?

Answer
Use the dichotomous key to answer the question.

Dichotomous Key

1a. Needle leaves: go to step 2

1b. Non-needles leaves: go to step 3

2a. Needles are grouped in clusters: pine tree

2b. Needles are individually arranged: spruce tree

3a. Simple (individual) leaves: go to step 4

3b. Compound leaves (leaflets): go to step 5

4a. Leaf edge is smooth and lobed: oak tree

4b. Left edge is rough and tooth-like: elm tree

5a. Leaflets are attached at one point: chestnut tree

5b. Leaflets are attached at many points: walnut tree



Examine the leaf.

Non-needle green leaf with compound leaves attached at the center.

What kind of tree is the leaf from?

Scientists examine the physical characteristics or traits of an organism when they use a dichotomous key.
Answered by Bot
The best characteristic that would identify the spiders as belonging to different species is the body shape. Specifically, the difference in body shape is described, with one spider having a "long, thin body" and the other spider having a "short, wide body."
Answered by Bot
The leaf is from a Chestnut Tree, as described in step 5a of the dichotomous key.
