A dichotomous key is a tool used by scientists to help identify organisms based on their characteristics. It is usually a series of questions with two possible answers (hence "dichotomous") that lead to the identification of the organism.
Step 1: Is the bird predominantly yellow or another color?
- If predominantly yellow, go to Step 2.
- If another color, this key may not help identify the bird.
Step 2: Does the bird have a distinct pattern on its wings or body?
- If yes, go to Step 3.
- If no, continue to the next step in the key.
A bird-watcher sees a small yellow bird in a tree. Explain to the bird-watcher how he can use a dichotomous key to identify the bird. Assume he does not know anything about dichotomous keys. Then, write two steps of a dichotomous key that would be helpful for the bird-watcher.(2 points)
