A researcher is interested in the geographic ranges of two types of mountain ground squirrels that both use similar resources and occupy a similar amount of space on the mountain. Species A lives on the upper slopes, while species B lives a bit further down. The researcher is able to find a few areas where only one type of squirrel lives. In the location where only species A is found, populations live at approximately the same altitude as they do when both species are present. However, in locations where only species B is found, its population extends much higher on the mountain than they do when species A is also present. What can the researcher infer from this information? O Species B has a larger realized niche than species. Species A has a larger fundamental niche than species B. Species A has a larger realized niche than species B. Species B has a larger fundamental niche than species A.

Question
A researcher is interested in the geographic ranges of two types of
mountain ground squirrels that both use similar resources and occupy a
similar amount of space on the mountain. Species A lives on the upper
slopes, while species B lives a bit further down. The researcher is able to
find a few areas where only one type of squirrel lives. In the location
where only species A is found, populations live at approximately the
same altitude as they do when both species are present. However, in
locations where only species B is found, its population extends much
higher on the mountain than they do when species A is also present.
What can the researcher infer from this information?
Species B has a larger realized niche than species A
Species A has a larger fundamental niche than species B.
Species A has a larger realized niche than species B.
Species B has a larger fundamental niche than species A.
