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) make it super short
A dichotomous key is a tool that helps identify organisms based on their characteristics.
1. Is the bird larger than a sparrow?
- If yes, go to step 2.
- If no, it may be a warbler.
2. Does the bird have black markings on its wings?
- If yes, it may be a black-throated green warbler.
- If no, it may be a pine warbler.
