Two ecology students are studying different things on Isle Royale.
The first student is keeping track of how the number of wolves on the island changes from year to year (but he is not looking at any other species). He is studying a wolf .
The second student is evaluating the interactions between moose and wolves on the island (but he is not considering any nonliving factors), and, as such, is studying a(n) .

In the given case, the first blank is filled with population and the second blank can be filled with community.

Explanation:

In the given case, as the first student is keeping a record of the number of wolves present in a given island and the factors affecting the number of wolves found from time to time on the island shows that the student is studying a population of the wolf.  

While the second student is assessing the association of the wolves with the other species like moose shows that the student is studying a community. A population refers to a single species group that thrives within a specific region at a specific time duration. On the other hand, a community refers to the combination of all the species populations found within a specific region.
