Final answer:
The option 'male wild turkeys growing larger beak ornaments' represents a physical change rather than a behavioral adaptation, making it the correct answer for what is NOT an example of a behavioral adaptation.
Step-by-step explanation:
The question asks which of the following is NOT an example of a behavioral adaptation:
- male wild turkeys growing larger beak ornaments
- rats eating only a single unfamiliar food at one time
- male moths gathering sodium to transfer to prospective mates
- grasshoppers digging a trench in which to hide
Behavioral adaptations are actions that organisms take to survive and reproduce. When considering the options, 'male wild turkeys growing larger beak ornaments' is not a behavioral adaptation but a physical or morphological change. Therefore, it does not fit the criteria of a behavior that has been modified for survival. In contrast, options b, c, and d describe actions, such as feeding behaviors, mate attraction strategies, and hiding methods, which are true behavioral adaptations. They present ways in which animals act to increase their fitness and chances of survival and reproduction.
