not quite sure how to approach this question, especially part 2.

Suppose a population of Whitesh in Pigeon Lake is changing according to the differential equation p' = p (p 5000)? 1. What is the long-term population size if the initial population is 10(0) = 10000? 2. Suppose the Whitesh attain that population size in (a), and suddenly some are harvested from the lake. What happens to the population in the long run
