The Falkland steamer duck (Tachyeres brachypterus) is a flightless bird endemic to the Falkland Islands in the South Atlantic Ocean. This species relies on the rocky shorelines for nesting and feeds primarily on marine mollusks and crustaceans. Predation on adults is relatively rare, though it is common for fledglings to be carried away by skua. A certain stretch of coast is settled by a population of 108 Falkland steamer ducks. The abundant nesting territory and rich feeding sites with abundant shellfish allow for rapid population growth. Soon, there is competition for nesting ground and food. The fraction of carrying capacity available for growth dwindles at point t in time to 0.081. At point t, given that the carrying capacity is 630, answer Question 3A and Question 3B. What growth model does this population exhibit? At point t, given that the carrying capacity is 630, answer Question 3A and Question 3B.
