Hunter is studying for his ecology test. Which fact would least likely show up in his notes?

Answers

Since you didn't give me a choice, I'll explain what ecology is. Ecology is the study of the ecosystem. Therefore, a question likely to be in the notes would be about how organisms interact with each other. 

Final answer:

The fact that would least likely show up in Hunter's ecology notes is the history of the microscope.

Explanation:

The fact that would least likely show up in Hunter's ecology notes is the history of the microscope. While understanding the history of scientific instruments is important in the context of science, it is not directly relevant to ecology. Ecology focuses on the study of the interactions between organisms and their environment, including concepts like ecosystems, food chains, and biodiversity.
