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)..........

Answer 1

A dichotomous key is a tool used to help identify different species of organisms based on their characteristics. It is like a series of yes-or-no questions that lead to the correct identification of the organism. In this case, the bird-watcher can use a dichotomous key to identify the small yellow bird he saw in the tree by answering a series of questions about the bird's physical characteristics.

Two steps of a dichotomous key that would be helpful for the bird-watcher to identify the small yellow bird are:

Step 1: Does the bird have a long, pointed beak?
- Yes: Go to Step 2.
- No: The bird is not a warbler.

Step 2: Does the bird have black markings on its wings?
- Yes: The bird is a black-throated green warbler (Setophaga virens).
- No: The bird is a yellow warbler (Setophaga petechia).
