Answer:
A forest of birds, insects, and squirrels
Explanation:
When referring to living beings, the term community refers to a group of populations of two or more different species that inhabit the same area.
An example of a community is a forest of birds, insects, and squirrels. Different species of birds, insects, and squirrels all live on the same territory - in a forest. This completely fits the definition of the community.
A hole in which a snake lives is just a place where an animal lives. A desert is a type of biome, which is a broader term than the community. A desert of sand, rocks, hawks, and snakes doesn't involve only species, but what they're surrounded with as well. This is why the third example is also incorrect.
