As part of our IB Biology Design we were set a topic: "Design an investigation on a habitat of your choice". I chose mountains, but I'm not sure what my research question should be! I did think of something like "How much does the amount of species on mountains vary at different altitudes?" but I'm a bit wary of that for some reason.

Do you have any ideas, please?

Sorry, but we really try not to help with homework/coursework on this website. I suggest you read a bit more about alpine ecosystems and make your own decision.
