Explanation:

For the first question: A population is a group of individuals of the same species in a specific area. Wolves on Isle Royale are the same species in one location, so it's a population.
For the second question: Density-independent factors affect populations regardless of size. Drought is an abiotic event not tied to population density, unlike competition, parasitism, or disease (density-dependent).

Answer:

C. population
B. drought
