Answer 1

C. Raccoons are generalists, and salamanders are specialists

Step-by-step explanation:

Generalist species are able to succed in in many different environments becasue they can make use of multiple resources, it is, they do NOT depend on a single resource or on a small set of resources for their survival (for example, they are omnivorous).

On the other hand, specialist species can succed only in very specific environmental conditions where they can find the resources they need.

The diet of the raccoons is very wide and consists of invertebrates, plants, vertebrates and even when they are close to humans they feed human waste. For this reason raccoons are generalists.

salamanders are specialists because they need specific conditions; wetland habitats with insects and worms that are its food source. Under conditions other than these parameters this species will have difficulty surviving.
